AB  - Electrochemically deposited nickel coatings from
sulfamate baths without/with lab-made biosilica (SiO2) particles on
the Si(100) substrate were produced. Different galvanostatic
regimes were used: direct current (DC), pulse current (PC), and
pulse-reverse current (PRC) regimes. The phase structure of the
synthesized silica nanoparticles from rice husks was obtained using
XRD and FE-SEM. The MMC-Ni/SiO2 and free Ni coatings were
characterized using FE-SEM, AFM, the micro indentation Vickers
technique, and the drop sessile method in order to investigate
structure, roughness, microhardness, and wettability. The optimal
deposition parameters were obtained with an emphasis on their
potential application as micro mounting coatings.

AB  - The electrochemical deposition of Zn onto Au from a choline chloride/ethylene glycol deep eutectic system containing different ZnCl2 concentrations has been investigated. The voltammetric results demonstrated that Zn electrodeposition commences in the zinc underpotential deposition (UPD) and proceeds through to the zinc overpotential deposition (OPD) region. The results of X-ray diffraction analysis revealed that the deposit prepared at a relatively low Zn overpotential of – 0.050 V vs. Zn was composed of cubic AuZn alloy. The morphology of the deposit has been characterized by means of a scanning electron microscope and displays a relatively compact and dendrite-free Zn/Au alloy deposit formed.

AB  - In this study, different forms of copper films were
electrodeposited (ED) on silicon wafer, copper and brass foils.
The effect of monocrystalline Si(111) surface cleaning method
and electrodeposition conditions and regimes (frequency in the
pulsating current (PC) regime, an addition of additives in
electrolyte for the constant galvanostatic (DC) regime, and
thickness) on surface morphology and wettability of copper films
was investigated. Optical microscopy equipped with highresolution camera, scanning electron microscopy (SEM) and an
atomic force microscopy (AFM) were used for thin film
characterization and to evaluate wettability of copper films. The
sessile drop method was used for the measurement of water
contact angle. According to the obtained results, choice of
electrolyte used in ED greatly affects wettability of copper films.
It was also shown that copper films electrodeposited from basic
sulfate electrolyte with varying current regimes frequencies,
thicknesses, and cathode types have opposite trends between
roughness parameter values and the water contact angle value.
Structural-morphological changes of a film or bulk solid surface
are key parameters in determining wettability properties and the
analysis of the wetting angle oscillations, but not the only one.

In the first step, Sn dendrites of various degree of ramification were electrodeposited by potentiostatically on cathodic potentials of –1200, –1400, –1600 and –1800 mV vs. Ag/AgCl. Electrodeposition of tin was performed from 20 g/l SnCl2 × 2H2O in 250 g/l NaOH electrolyte at the room temperature on Cu electrodes. In the second step, Pd was electrodeposited galvanostatically at a current density of –5 mA cm-2 on the electrodes with electrodeposited Sn dendrites. Electrodeposition of Pd was performed from 1 M NH4Cl and 0.01 M PdCl2 at the room temperature. The processes of electrochemical deposition of Sn and Pd were performed with amounts of the electricity of 400 and 267 mC, giving an atomic ratio synthesized the electrocatalysts of 60 at.% Sn‒40 at.% Pd.

AB  - Ova studija je fokusirana na pronalaženje novih načina sinteze katalizatora na
bazi platine koji pokazuju dobru efikasnost za reakciju oksidacije metanola.
Nanočestice PtZn, PtSn i PtSnZn su sintetizovane korišćenjem poliol metode uz
pomoć mikrotalasnog zagrevanja i deponovane na ugljeničnu podlogu Vulcan
XC-72R. Elektrohemijsko ponašanje sintetizovanih katalizatora je ispitivano
korišćenjem ciklične voltametrije i hronoamperometrijske tehnike.
Fizičkohemijska svojstva dobijenih katalizatora su okarakterisana
transmisionom elektronskom mikroskopijom (TEM), termogravimetrijskom
analizom (TGA) i energetsko disperzivnom spektroskopijom (EDS). Prema
TEM analizi svi katalizatori imaju male čestice prilično slične veličine između 1
i 3 nm. Dobijeni rezultati su potvrdili uspešnu sintezu katalizatora na bazi Pt.
Dodavanje Zn i Sn u Pt katalizator značajno poboljšava aktivnost oksidacije
metanola u poređenju sa Pt/C referentnim katalizatorom. Testovi stabilnosti
takođe dokazuju slabije trovanje i ukazuju na bolju stabilnost i veću toleranciju
na CO intermedijere. Uočena visoka katalitička aktivnost i dobra stabilnost u
reakciji oksidacije metanola sintetizovanih katalizatora mogu se pripisati
veoma efikasnoj mikrotalasnoj sintezi i dobro izbalansiranom sadržaju Zn i Sn
kao legirajućih metala.
AB  - This study is focused on novel ways for creating Pt alloy catalysts that are more
effective for the methanol oxidation reaction. PtZn, PtSn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and
were supported on high surface area carbon Vulcan XC-72R material. The
electrochemical behaviour of synthesized catalysts was investigated utilizing
the cyclic voltammetry and chronoamperometric technique. To determine the catalyst's physicochemical characteristics, transmission electron microscopy
analysis (TEM), energy dispersive spectroscopy (EDS) and thermogravimetric
analysis (TGA) were used. According to TEM analysis all catalysts have small
particles of rather similar size between 1 and 3 nm. The obtained results
confirmed the successful synthesis of Pt-based catalyst. Addition of Zn and Sn
to Pt significantly improves methanol oxidation activity in comparison to Pt/C
benchmark catalyst. Stability tests also prove the lower poisoning and indicate
better stability and higher tolerance to CO-like intermediaries. The observed
high catalytic activity and good stability in the methanol oxidation reaction of
synthesized catalyst can be ascribed to the very efficient microwave synthesis
and well-balanced content of Zn and Sn as alloying metal.

i 3 nm. Dobijeni rezultati su potvrdili uspešnu sintezu katalizatora na bazi Pt.
Dodavanje Zn i Sn u Pt katalizator značajno poboljšava aktivnost oksidacije
metanola u poređenju sa Pt/C referentnim katalizatorom. Testovi stabilnosti
takođe dokazuju slabije trovanje i ukazuju na bolju stabilnost i veću toleranciju
na CO intermedijere. Uočena visoka katalitička aktivnost i dobra stabilnost u
reakciji oksidacije metanola sintetizovanih katalizatora mogu se pripisati
veoma efikasnoj mikrotalasnoj sintezi i dobro izbalansiranom sadržaju Zn i Sn
kao legirajućih metala., This study is focused on novel ways for creating Pt alloy catalysts that are more
effective for the methanol oxidation reaction. PtZn, PtSn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and
were supported on high surface area carbon Vulcan XC-72R material. The
electrochemical behaviour of synthesized catalysts was investigated utilizing
the cyclic voltammetry and chronoamperometric technique. To determine the catalyst's physicochemical characteristics, transmission electron microscopy
analysis (TEM), energy dispersive spectroscopy (EDS) and thermogravimetric
analysis (TGA) were used. According to TEM analysis all catalysts have small
particles of rather similar size between 1 and 3 nm. The obtained results
confirmed the successful synthesis of Pt-based catalyst. Addition of Zn and Sn
to Pt significantly improves methanol oxidation activity in comparison to Pt/C
benchmark catalyst. Stability tests also prove the lower poisoning and indicate
better stability and higher tolerance to CO-like intermediaries. The observed
high catalytic activity and good stability in the methanol oxidation reaction of
synthesized catalyst can be ascribed to the very efficient microwave synthesis
and well-balanced content of Zn and Sn as alloying metal.",

AB  - Due to their high electrocatalytic activity, Pt-based materials are widely investigated as electrocatalysts for the electro-oxidation of small organic molecules for fuel cells technology applications, contributing to the potential reduction of fossil fuel use in the near future. In addition to methanol, formic acid has also gained increasing attention as a potential fuel for direct fuel cells due to lower toxicity, non-flammability and a lower storage cost. The electro-oxidation of formic acid on Pt-based thin films is taking place predominantly via indirect pathway, through the dehydrogenation reaction of formic acid, with the formation of CO as a poisoning species. The activity of electrocatalysts is dependent both on surface structure and surface orientation in terms of the arrangement of the atoms at the surface. Controlled heat treatment led to the rearrangement of surface atoms thus enhancing the catalytic properties. In order to investigate changes in morphology before and after thermal annealing, Pt/CrNi catalysts were characterized using an atomic force microscope (AFM). The performance of all catalysts was tested in formic acid electro-oxidation reaction. The synergistic effect of individual metallic components, in the designed catalyst, resulted in high activity and exceptional stability. The approach demonstrated in this work may promote the development of new generation of high-performance catalysts for use in direct formic acid fuel cells (DFAFCs).

AB  - Nanostructured materials present unique properties as electrocatalysts for various industrial needs such as electrochemical energy conversion and storage. Aiming to enhance the electrocatalytic properties of Pd towards the electrochemical oxidation of ethanol, we used the electrodeposited Sn dendrites as a sub-layer for Pd. We tested the resulting Sn-Pd electrocatalysts for ethanol oxidation reaction (EOR). It was obtained that different morphological characteristics of Sn contribute to and determine Pd electrochemical behavior in EOR. By varying the amount of Sn loading prepared in the potentiostatic regime and keeping constant Pd loading, a series of Sn-Pd electrocatalysts with various ratios of Sn and Pd were synthesized and among them, Sn0.6-Pd0.4 showed to be the most active and poisoning tolerant catalyst in EOR. It was pointed out that optimization of composition and morphology assures well synergy of Sn with Pd towards EOR and at the same time demonstrates the guide for the design of novel materials with specific properties. Therefore Sn-Pd catalysts have emerged as a suitable and promising anode material for direct alcohol fuel cells.

AB  - Procesi nukleacije i rasta dendrita kalaja iz alkalnog hidroksidnog elektrolita su istraženi hronoamperometrijom i skenirajućom elektronskom mikroskopskom (SEM) analizom taloga potenciostatski elektrohemijski istaloženih na selektivnim katodnim potencijalima. Za određivanje tipa nukleacije korišćen je model Šarifkera i Hilsa (SH) zasnovan na trodimenzionalnoj nukleaciji sa difuziono kontrolisanim rastom. Bez obzira na primenjeni katodni potencijal, dobijene bezdimenzionalne zavisnosti su bile niže od teorijskih predviđanja za progresivni tip nukleacije. Sa druge strane, morfologija dendrita kalaja je snažno zavisila od primenjenog katodnog potencijala, te igličasti ili dendriti nalik paprati su bili formirani potenciostatskim režimom elektrohemijskog taloženja. Na osnovu morfološke analize Sn dendrita elektrohemijski istaloženih različitim količinama elektriciteta, zaključeno je da nukleacija Sn iz ispitivanog elektrolita ipak sledi progresivni tip, i da se odstupanje od teorijskih predviđanja za ovaj tip može pripisati upotrebi kompleksnog elektrolita za elektrohemijsko taloženje kalaja.
AB  - The processes of nucleation and growth of tin dendrites from alkaline hydroxide electrolyte have been investigated by chronoamperometry and by the scanning electron microscopic (SEM) analysis of the deposits potentiostatically electrodeposited at the selected cathodic potentials. The Scharifker and Hills (SH) model based on three dimensional nucleation with diffusion controlled growth was used for a determination of a nucleation type. Irrespective of the applied cathodic potential, the obtained dimensionless dependencies were lower than the theoretical predictions for the progressive type of nucleation. On the other hand, morphology of Sn dendrites strongly depended on the applied cathodic potential, and either the needle-like or the fern-like dendrites were formed by the potentiostatic regime of electrodeposition. On the basis of the morphological analysis of Sn dendrites electrodeposited with various amounts of the electricity, it is concluded that nucleation of Sn from the examined electrolyte still follows the progressive type, and that the deviation of the theoretical predictions for this type can be attributed to use of complex electrolyte for Sn electrodeposition.

On the other hand, morphology of Sn dendrites strongly depended on the applied cathodic potential, and either the needle-like or the fern-like dendrites were formed by the potentiostatic regime of electrodeposition. On the basis of the morphological analysis of Sn dendrites electrodeposited with various amounts of the electricity, it is concluded that nucleation of Sn from the examined electrolyte still follows the progressive type, and that the deviation of the theoretical predictions for this type can be attributed to use of complex electrolyte for Sn electrodeposition.",

AB  - One of the most popular alternative sources of energy are direct methanol fuel cells (DMFCs) with platinum-based catalysts due to their non-toxicity, reduced emissions of hazardous pollutants and high energy density. However, significant challenges of the scientific community related to Pt catalysts are the high cost, depletable resources and formation of poisoning species i.e. CO, during the methanol oxidation reaction. To reduce the amount of expensive Pt and susceptibility of Pt to poisoning species and simultaneously improve its catalytic performance, recent studies are focusing on the synthesis of Pt alloys in which a certain amount of platinum is replaced with less expensive metals such as Ru, Sn, Ni, Cu, Rh and Co. The usage of carbon (Vulcan XC-72R) for catalyst support enables high dispersion of metal, high surface area and good electrical conductivity improving overall performances of DMFCs. In this work, PtZn/C and PtSnZn/C catalysts were synthesized by the microwave-assisted polyol method. The structure and morphology of the catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TG) and X-ray diffraction (XRD) analysis. The activity and stability of synthesized catalysts for methanol oxidation in 0.5 M sulfuric acid were investigated. It was demonstrated that the activity of the platinum catalysts was improved thanks to the synergistic effects caused by the addition of different metals, such are bifunctional and electronic effects.

development of an efficient and economical catalyst is a crucial step. Reducing the

chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine
the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission
electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were
used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the

The electrocatalytic activity of Sn-Pd catalysts were evaluated for EOR in alkaline solution using cyclic voltammetry (CV) and chronoamperometric (CA) measurements. The highest activity and anti-poisoning ability exhibited Sn0.67-Pd0.33 catalyst due to the better utilization of Pd. At Sn0.67-Pd0.33 catalyst Sn better contribute Pd to oxidize chemisorbed species by providing adsorbed OH- species, thereby enabling well synergy of Sn with Pd

AB  - The processes of nucleation and growth of tin dendrites from the alkaline hydroxide solution have been investigated. Nucleation of tin was examined by chronoamperometry at the cathodic potentials which belonged to various positions at the polarization curve. The morphology of potentiostatically electrodeposited tin dendrites with various amounts of the electricity was characterized by scanning electron microscopy (SEM) technique. Depending on the cathodic potential applied for Sn electrodeposition, the following forms of Sn dendrites were obtained: the needle-like, the spear-like and the fern-like dendrites of various degree of ramification. Combining Sharifker and Hills (SH) model for a determination of nucleation type and results of morphological analysis of Sn dendrites, it is concluded that nucleation of Sn from the alkaline hydroxide solution follows the progressive type of nucleation.
AB  - Analizirani su procesi nukleacije i rasta dendrita kalaja iz alkalnog hidroksilnog rastvora. Nukleacija kalaja je bila ispitana hronoamperometrijom na katodnim potencijalima koji su pripadali različitim pozicijama na polarizacionoj krivoj.

abstract = "The processes of nucleation and growth of tin dendrites from the alkaline hydroxide solution have been investigated. Nucleation of tin was examined by chronoamperometry at the cathodic potentials which belonged to various positions at the polarization curve. The morphology of potentiostatically electrodeposited tin dendrites with various amounts of the electricity was characterized by scanning electron microscopy (SEM) technique. Depending on the cathodic potential applied for Sn electrodeposition, the following forms of Sn dendrites were obtained: the needle-like, the spear-like and the fern-like dendrites of various degree of ramification. Combining Sharifker and Hills (SH) model for a determination of nucleation type and results of morphological analysis of Sn dendrites, it is concluded that nucleation of Sn from the alkaline hydroxide solution follows the progressive type of nucleation., Analizirani su procesi nukleacije i rasta dendrita kalaja iz alkalnog hidroksilnog rastvora.

AB  - This work highlights a simple and efficient approach for the development of
PtZn catalyst materials with tunable content of Zn. Nanoparticles of PtZn
deposited on high surface area carbon Vulcan XC-72R material were
synthesized by microwave-assisted polyol method, giving control over the size
and dispersion of nanoparticles. Cyclic voltammetry and electrooxidation of
adsorbed CO were used to investigate the electrochemical behavior of
synthesized catalysts: PtZn/C (90:10); PtZn/C (85:15) and PtZn/C (75:25). It
was found that PtZn/C catalysts have high electrocatalytic performance in
methanol oxidation reactions. In comparison to the corresponding catalyst with
the different Zn loading, it was concluded that PtZn (90:10)/C catalyst had
better activity compared to PtZn/C (85:15) and PtZn/C (75:25) catalysts. The
observed high catalytic activity in the methanol oxidation reaction of
synthesized catalysts can be ascribed to the very efficient microwave synthesis
and well-balanced content of Zn as alloying metal.

AB  - Pollution caused by the usage of fossil fuels is a consequence of industrialization, urbanization, and technological development, having a huge impact on the environment and human health. Thus, one of the biggest challenges that currently confront not only the scientific community but also humanity is reducing the use of fossil fuels, as well as the production and consumption of energy using renewable energy sources. In the last decades, small organic molecules such as methanol, ethanol and formic acid have attracted attention due to their properties that make them convenient for use in fuel cells. Among other precious metals, Pt is the most investigated as a promising catalyst for the anodic electrooxidation reaction of small organic molecules. However, high price, scarceness and susceptibility to poisoning are some of the limiting factors for the commercial use of pure Pt. There are two ways to mitigate those problems: lower the content of a noble metal present or make the catalyst more active for the particular reaction. To address the first problem nanocatalyst, produced by the deposition of platinum onto high surface area supports were introduced. A far greater challenge is to modify the catalyst to make it not just more active, but more stable as well, for a particular reaction. It is now well known that bimetallic catalysts fulfill these requirements quite well, and currently, they are widely used in many catalytic and electrocatalytic processes. In this study, a thin Pt film was electrochemically deposited on nickel support (Pt/Ni) and afterward subjected to the controlled thermal treatment in an attempt to reduce the proneness of Pt to poisoning species (CO) and therefore improve its catalytic performance at low potentials in the formic oxidation reaction. All produced catalysts were electrochemically characterized using cyclic voltammetry and oxidation of CO monolayer, while the influence of thermal annealing on the morphology was monitored using an atomic force microscope (AFM). Finally, catalyst performance was tested in a formic acid electrooxidation reaction. The obtained results clearly show that the exceptional activity for formic acid electrooxidation, measured on annealed Pt/Ni is a direct consequence of the nature of the substrate which manifests itself after controlled heat treatment through surface reconstruction and bifunctional effect.

AB  - Polymer electrolyte membrane fuel cells (PEMFCs) are pure electrochemical energy converters that are key components of energy sources for vehicles and for stationary and portable energy suppliers. Searching for a good catalyst for the ethanol oxidation reaction is one of the most significant issues in material science. To increase the economic potential of fuel cell technology, catalyst must be extremely active, stable, and inexpensive. Due to its high catalytic activity, structural and chemical stability, and widespread use in commercial fuel cells, platinum is still the material of choice for making cathodes. Although there is extensive continuing research to reduce the Pt concentration while keeping the high catalytic activity, its high cost remains a barrier to a wider adoption of fuel cell technology.Therefore, the potential for cost reduction lies in the optimization of the catalyst, i.e. obtaining the maximum catalytic efficiency with the lowest possible content of noble metals. The focus of this research will be on novel synthesis techniques for PtSnZn catalysts with better efficiency and durability for the ethanol oxidation reaction. This research demonstrates the potential of studying new PtSnZn catalytic materials as catalysts for the oxidation of ethanol. This study used the microwave assisted polyol technique to create PtZn and PtSnZn nanoparticles supported on high surface area carbon Vulcan XC-72R material. By using cyclic voltammetry, electro-oxidation of adsorbed CO, and the chronoamperometric method, the electrochemical behavior of synthesized catalysts was examined. X-ray diffractometry, transmission electron microscopy analysis and thermogravimetric analysis were applied to obtain the physicochemical properties of the catalyst. The advantages of microwave synthesis and carefully balanced metal alloying in the PtSnZn/C catalysts led to a high catalytic activity of the synthesized catalyst in the ethanol oxidation reaction compared to the Pt/C catalyst.

AB  - Tin dendrites found wide application in various industries.1 They can be obtained by both non-electrochemical and electrochemical methods of synthesis. In this study, they were produced by a galvanostatic regime of electrolysis from alkaline hydroxide solution at a current density of –3 mA cm–2, 1.5 times larger than the limiting diffusion current density, with an amount of the electricity of 200 and 400 mC. In the dependence of an amount of the passed electricity, Sn dendrites of various morphology and crystal orientation were obtained: the fern-like dendrites predominantly oriented in (220), (440) crystal planes are obtained with 200 mC and the spear-like and the dendrites with prismatic branches showing the strong (200),(400) preferred orientationwere obtained with 400 mC.
The strong correlation between morphology and structure of Sn dendrites is established and it can be explained by analysis of chronopotentiometry response obtained at the given current density and by morphological and structural analyses of Sn dendrites obtained by a potentiostatic regime at cathodic potentials corresponding to values attained after the passed amount of the electricity of 200 and 400 mC. The chronopotentiometry response after spent 200 mC was dominantly in the (–1600 –1740) mV vs. Ag/AgCl range, and the fern-like dendrites with the strong (220), (440) preferred orientation were obtained in this potential range. After spent 400 mC, the chronopotentiometry response was about –1200 mV vs. Ag/AgCl, and the spear-like and the dendrites with prismatic branches with the strong (200),(400) preferred orientationwere obtained at this cathodic potential.

AB  - A series of bimetallic Sn-Pd catalysts were prepared by a template-free two step electrodeposition method. According to this method, Sn was electrodeposited firstly in potentiostatic or galvanostatic regime on Cu electrodes in the form of dendrites, then Pd was galvanostatically electrodeposited in the second step on the electrode with the electrodeposited Sn dendrites. The produced Sn-Pd electrocatalysts were compared with an electrocatalyst obtained by Pd electrodeposition on a bare Cu electrode. The morphological and elemental analysis of Sn-Pd and Pd electrocatalysts was performed by means of scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) techniques. The dendrites of various shapes and degree of branching were obtained by Sn deposition depending on electrodeposition regime, while Pd was electrodeposited in a form of compact Pd islands on both Sn dendrites and the Cu electrode. Cyclic voltammetry (CV) was applied for the electrochemical examination of Sn-Pd and Pd catalysts towards the ethanol oxidation reaction (EOR) in the alkaline solution. The electrocatalyst Sn0.6-Pd0.4 with an atomic ratio of 60 at.% Sn-40 at.% Pd showed higher oxidation efficiency and better tolerance towards intermediate species in EOR than the other examined electrocatalysts . It was shown that the lower fraction of Pd, relative to Sn, was crucial to achieving optimal synergy of Sn with Pd thus contributing to enhanced electrochemical behavior regarding EOR.
AB  - Серија на биметални катализатори со различни односи на Sn:Pd беа подготвени со методот

Според овој метод, прво Sn во форма на дендрити беше нанесен електрохемиски во потенциостатски или галваностатски режим врз површината на Cu-електроди. Потоа, во вториот чекор, Pd беше галваностатски нанесен на електродата врз нанесените дендрити од Sn. Вака добиените Sn:Pd-електрокатализатори беа споредени со електрокатализатори добиени со нанесување на Pd на чиста Cu електрода.

Дендритите со различни форми и различен степен на разгранување беа добиени со нанесување Sn во зависност од режимот на електродепозиција, додека Pd беше нанесен во форма на компактни острови врз дендритите од Pd и Sn на површината на Cu-електродата.

AB  - Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn‒40 at.% Pd suitable for 
potential application in direct ethanol fuel cells were synthesized using a novel two-step electrodeposition method. First, Sn was electrodeposited in various forms of dendrites, from spear-like and needle-like to individual fern-like dendrites to a network of intertwined fern-like dendrites, by varying the cathodic potential and then performing electrodeposition of Pd at a constant current 
density in the second step. A morphological and elemental analysis of Sn and Sn-Pd electrocatalysts was performed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS) techniques, while the size of Sn dendrites was analyzed using the particle size distribution (PSD) method. Cyclic voltammetry (CV) and chronoamperometry were applied in order to study the catalytic behavior of Sn-Pd electrocatalysts in the ethanol oxidation reaction (EOR), while CO stripping was used to estimate the antipoisoning capability of the electrocatalysts. The Sn surface morphology of the sub-layer was highly correlated with the electrocatalytic activity of the examined Sn-Pd electrocatalysts. The high activity it presented towards the EOR showed the suitability of the Sn-Pd electrocatalyst constructed from individual fern-like Sn dendrites as a sub-layer. Compared to Pd alone, this Sn-Pd catalyst showed more than 3 times higher activity and improved EOR kinetics. This enhancement in the catalytic activity of the Sn-Pd electrocatalysts is attributed to both the morphological characteristics of Sn as a sub-layer and the bifunctional effect.

AB  - Correlation among morphological, structural and hardness characteristics of electrodeposited
copper coatings is presented in this review paper. Cu coatings were produced applying constant galvanostatic (DC) and pulsating current (PC) regimes on hard silicon (Si(111)) and brass substrates. The parameters of the electrochemical deposition which include the kinds of electrolyte
and cathode, the coating thickness and the electrolyte stirring, as well as the parameters defining
PC regime, such as the average current density and the current density amplitude, were analyzed.
Morphology and structure of Cu coatings were examined by scanning electron microscope (SEM),
atomic force microscope (AFM) and by X-ray diffraction (XRD), while hardness was examined by
Vickers microindentation. The coatings of Cu on both Si(111) and brass cathodes belong to “soft film (coating) on hard substrate” composite hardness system, and the Chicot–Lesage (C–L) composite hardness model was applied to estimate a hardness of the Cu coatings. Analyzing the examined parameters and regimes of electrodeposition, the critical relative indentation depth (RID)c of 0.14 has been defined by the C–L model. Based on done analyses, it is shown that this RID value, separating a zone where measured hardness corresponds to the coating hardness and a zone where it is necessary to apply the C–L model to determine an absolute hardness of the Cu coatings, has an universal character for the electrolytically produced Cu coatings on Si(111) and brass substrates.

AB  - This work highlights the potential for the synthesis of new PtSnZn catalysts with enhanced efficiency and durability for methanol oxidation reaction (MOR) in low-temperature fuel cells. In this research, PtZn and PtSnZn nanoparticles deposited on high surface area Vulcan XC-72R Carbon support were created by a microwave-assisted polyol method. The electrochemical performances of synthesized catalysts were analyzed by cyclic voltammetry and by the electrooxidation of adsorbed CO and the chronoamperometric method. The physicochemical properties of obtained catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TGA) analysis, energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD). The obtained findings showed the successful synthesis of platinum-based catalysts. It was established that PtSnZn/C and PtZn/C catalysts have high electrocatalytic performance in methanol oxidation reactions. Catalysts stability tests were obtained by chronoamperometry. Stability tests also confirmed decreased poisoning and indicated improved stability and better tolerance to CO-like intermediate species. According to activity and stability measurements, the PtSnZn/C catalyst possesses the best electrochemical properties for the methanol oxidation reaction. The observed great electrocatalytic activity in the methanol oxidation reaction of synthesized catalysts can be attributed to the beneficial effects of microwave synthesis and the well-balanced addition of alloying metals in PtSnZn/C catalysts.

AB  - The influence of chronopotentiometry response on the morphology and structure of galvanostatically synthesized tin dendritic
particles has been investigated. Sn dendrites were electrodeposited at the current density 1.5 times larger than the limiting diffusion
current density (− 3 mA cm−
2) with various amounts of the electricity (200 and 400 mC), and the obtained morphology
and structure of the particles were characterized by SEM and XRD techniques, respectively. The strong effect of the amount
of spent electricity on the morphology and structure of the particles was observed, and it is explained by morphological and
structural analysis of Sn particles produced potentiostatically at various cathodic potentials selected to be in line with the
recorded chronopotentiometry response. The strong correlation among chronopotentiometry response, morphology, and
structure of the Sn dendrites was established. The spear-like and the dendrites with prismatic branches possessed the strong
(200),(400) preferred orientation, and they were obtained with a chronopotentiometry response of about − 1200 mV vs. Ag/
AgCl. The chronopotentiometry responses in the − 1210 ÷ − 1740 mV vs. Ag/AgCl range caused a formation of the fern-like
dendrites with the strong (220),(440) preferred orientation. Based on the obtained results, it follows that the chronopotentiometry
analysis represents good diagnostic criteria for obtaining Sn powder particles of desired morphology and structure.
