AB  - Lab-made biosilica (SiO2) nanoparticles were obtained from waste biomass (rice husks) and used as eco-friendly fillers in the production of nickel matrix composite films via the co-electrodeposition technique. The produced biosilica nanoparticles were characterized using XRD, FTIR, and FE-SEM/EDS. Amorphous nano-sized biosilica particles with a high SiO2 content were obtained. Various current regimes of electrodeposition, such as direct current (DC), pulsating current (PC), and reversing current (RC) regimes, were applied for the fabrication of Ni and Ni/SiO2 films from a sulfamate electrolyte. Ni films electrodeposited with or without 1.0 wt.% biosilica nanoparticles in the electrolyte were characterized using FE-SEM/EDS (morphology/elemental analyses, roundness), AFM (roughness), Vickers microindentation (microhardness), and sheet resistance. Due to the incorporation of SiO2 nanoparticles, the Ni/SiO2 films were coarser than those obtained from the pure sulfamate electrolyte. The addition of SiO2 to the sulfamate electrolyte also caused an increase in the roughness and electrical conductivity of the Ni films. The surface roughness values of the Ni/SiO2 films were approximately 44.0%, 48.8%, and 68.3% larger than those obtained for the pure Ni films produced using the DC, PC, and RC regimes, respectively. The microhardness of the Ni and Ni/SiO2 films was assessed using the Chen-Gao (C-G) composite hardness model, and it was shown that the obtained Ni/SiO2 films had a higher hardness than the pure Ni films. Depending on the applied electrodeposition regime, the hardness of the Ni films increased from 29.1% for the Ni/SiO2 films obtained using the PC regime to 95.5% for those obtained using the RC regime, reaching the maximal value of 6.880 GPa for the Ni/SiO2 films produced using the RC regime.

AB  - Electrodeposition of copper from deep eutectic solvents (DES) based on a mixture of choline chloride and
ethylene glycol containing CuCl2⋅2H2O at 50 ◦C and 80 ◦C was studied. Electrochemical reduction/oxidation of
Cu(II)/Cu(0) on glassy carbon (GC) and palladium (Pd) electrodes was investigated by cyclic voltammetry (CV)
and square wave voltammetry (SWV) emphasizing that this process takes place through two steps, Cu(II) ↔ Cu(I)
and Cu(I) ↔ Cu(0). The CV results showed that in chloride-rich DES electrolytes, the increased presence of chloro
ligands raises the overpotential required for Cu electrodeposition. The electrochemical impedance spectroscopy
(EIS) results indicate simultaneous electrodeposition of Cu and electrosorption of large cations on electrodeposited
Cu on both GC and Pd substrates. Scanning electron microscopy (SEM) results showed that Cu grains of
approximately 1 μm were obtained by electrodeposition of Cu on both Pd and GC, whereby better coverage by
electrodeposited Cu was obtained on Pd than on GC. Cu electrodeposited on Pd was relatively uniform and
smooth, but porous, while Cu electrodeposited on GC was dispersed in small agglomerates. Energy-dispersive Xray
spectroscopy (EDS) of Cu electrodeposited on Pd detected the dominant presence of Cu with the possibility of
the formation of CuPd alloy. The presence of CuPd alloy face-centred cubic structures is confirmed by X-ray
diffraction (XRD) along with metallic Cu.

AB  - The alkaline electrolytes of zinc are widely used in a Zn-air secondary batteries which represent promising candidate for energy storage with many advantages relative to the other types, such as Li-air, Al-air, and Mg-air batteries. These advantages are related with an abundance of Zn, low toxicity, and low cost, as well as by the fact that Zn possess a relatively high specific energy density. One of the largest problems in a development of Zn-air batteries is dendritic growth caused by the uneven deposition of zinc in the charging process. The solving of this problem implies the good knowledge of all phenomena related with Zn deposition, and regarding it, this study aims to establish a correlation between morphology and structure of electrolytically produced Zn irregular forms, especially Zn dendrites.

U ovom radu prikazana je galvanostatska priprema Pd iz rastvora bez surfaktanata. Analiza skenirajuće elektronske mikroskopije pokazala je nanosfere Pd veličine do 300 nm. Uporednim ispitivanjem oksidacije metanola i etanola utvrđena je veća aktivnost katalizatora u rastvoru LiOH u odnosu na rastvor NaOH usled formiranja klastera OHad ‒ katjona. Naime, nekovalentna interakcija i formiranje OHad ‒ katjonskih klastera određuju interakciju alkoholne OH grupe sa OH grupom na površini Pd, i posledično određuju aktivnost Pd u ispitivanim reakcijama. Može se zaključiti da izbor katjona alkalnih metala reguliše elektrokatalitičku aktivnost i da se može smatrati jednim od bitnih parametara u elektrokatalizi.
AB  - Rationally designing of noble metal materials are of great interest for supporting their applications in the field of electrocatalysis. In this contribution, we demonstrated the galvanostatic preparation of Pd from surfactant free solution. Scanning electron microscopy analysis revealed Pd nanospheres of up to 300 nm. Comparative study of methanol and ethanol electrochemical oxidation reveals higher catalyst activity in LiOH solution in regard to NaOH solution due to the formation of OHad ‒ cation clusters. Namely non-covalent interaction and formation of OHad ‒ cation clusters govern the interaction of the alcohol OH group with the OH group on the Pd surface, and in turn determined its electrooxidation activity on Pd. It was pointed out that the choice of alkali metal cations regulate the electrocatalytic activity and can be considered as one of the tuning parameter in electrocatalysis.

AB  - Electrodeposition of copper from an eutectic mixture based on choline chloride and ethylene glycol
containing copper(II) chloride salt at 50 °C was investigated. It was shown that electrochemical
reduction process of Cu(II) proceeds via two steps, Cu(II) → Cu(I) and Cu(I) → Cu(0).
Electrodeposits were obtained by potentiostatic electrolysis and analyzed by scanning electron
microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDS). SEM results showed that the
electrodeposited Cu on Pd was relatively uniform and smooth, with Cu grains of approximately 1
micrometer. EDS analysis of the Pd electrode surface after Cu electrodeposition revealed that Cu is dominating in the deposit. The presence of CuPd alloy, along with metallic Cu on the Pd surface is confirmed by X-ray diffraction (XRD).

AB  - Zinc-air batteries belong to the group of green and sustainable energy storage systems, and as such, they attract a huge attention of both academic and technological communities. For this system, the alkaline electrolytes of zinc with high concentrations of ZnO and KOH are used. Morphology of zinc electrodeposits is characterized by the scanning electron microscopy (SEM) technique, and it was found that it depended on an overpotential of the electrodeposition with a strong contribution of a length of the electrodeposition time on the final shape. Variety of morphological shapes was observed: irregular and regular grains including those hexagonal shape were predominately formed at the overpotential belonging to the plateau of the limiting diffusion current density. The compact both regular and irregular dendrites were formed at this overpotential with the longer electrodeposition time. The 2D (two-dimensional) and 3D (three-dimensional) dendrites were formed at overpotentials outside the plateau of the limiting diffusion current density, in the zone of the rapid growth of the current density with the increase of the overpotential. In this zone, hydrogen evolution reaction as the second reaction to Zn electrolysis at high overpotentials started to take place. It is manifested by the appearance of craters on the surface of the electrode, which originate from detached hydrogen bubbles. All morpholical forms were explained and discussed applying the basic laws of electrocrystallization.

AB  - The lab-made ferrite-aluminium layered double oxide (Fe/Al LDO) nanoparticles were used as reinforcement in the production of copper matrix composite coatings via the electrodeposition route in this study. The Cu coatings electrodeposited galvanostatically without and with low concentrations of Fe/Al LDO nanoparticles were characterized by SEM (morphology), AFM (topography and roughness), XRD (phase composition and texture), Vickers microindentation (hardness), and the static sessile drop method (wettability). All Cu coatings were fine-grained and microcrystalline with a (220) preferred orientation, with a tendency to increase the grain size, the roughness, and this degree of the preferred orientation with increasing the coating thickness. The cross-section analysis of coatings electrodeposited with Fe/Al LDO nanoparticles showed their uniform distribution throughout the coating. Hardness analysis of Cu coatings performed by application of the Chicot-Lesage (C-L) composite hardness model showed that Fe/Al LDO nanoparticles added to the electrolyte caused a change of the composite system from “soft film on hard cathode” into “hard film on soft cathode” type, confirming the successful incorporation of the nanoparticles in the coatings. The increase in roughness had a crucial effect on the wettability of the coatings, causing a change from hydrophilic reinforcement-free coatings to hydrophobic coatings obtained with incorporated Fe/Al LDO nanoparticles.

AB  - Correlation between morphology of electrolytically produced copper thin films and their hardness has been considered. The Cu films were electrodeposited by galvanostatic (DC) and by the pulsating current (PC) regimes on cathodes of limiting values of hardness (Cu, brass, and Si(111)) from the basic sulfate electrolytes without and with addition of leveling/brightening additives, without and with various ways of electrolyte stirring (ultrasound and magnetic stirring), and characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques. Hardness of Cu films was determined by microindentation and by application of composite hardness models (CHMs), such as Cheng–Gao (C–G) and Korsunsky (K), with the aim to eliminate a contribution of cathode hardness in the measured film hardness and to determine the absolute hardness of the Cu films. The fine-grained films obtained from the basic sulfate electrolyte were harder than the smooth film obtained from the electrolyte with additives and that obtained by the PC regime, indicating that the PC produced film represents transitional form between these two types of the films. The obtained values of the absolute film hardness in the 1.135–1.647 GPa range were in line with already published values for the electrolytically produced Cu thin films, clearly indicating on successful implementation of CHMs in determination of the absolute hardness of thin films. Correlation between morphology and hardness of Cu films was discussed by the basic laws of electrocrystallization and phenomena on boundary among grains during microindentation processes.

AB  - The electrochemical deposition of zinc/gold dendrite-free alloys was achieved from deep eutectic solvents based on a mixture of choline chloride and ethylene glycol, without using any additives. Potentiostatic electrodeposition was carried out at relatively low Zn electrodeposition overpotential at different Zn(II) concentrations. Insight into the electrochemical mechanism of the Zn electrodeposition was revealed by cyclic voltammetry (CV) and chrono- amperometry (CA). The morphology and structure of the obtained electrodeposits were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), while the elemental analysis was determined by energy dispersive spectroscopy (EDS) technique. The CV results showed that Zn electrodeposition commences with zinc underpotential deposition (UPD) and proceeds through the zinc overpotential deposition (OPD) region. The deposition potential of the Zn/Zn(II) couple shifts towards more positive value with increased Zn(II) concentration. CA analysis demonstrated that in the zinc OPD region, 3D progressive nucleation starts, followed by 3D growth of depositing zinc. Morphological analysis revealed that electrodeposition commences with the formation of compact Zn islands and proceeds through dendrite-free zinc/gold alloys formed. A formation of several intermetallics, namely cubic AuZn3 and AuZn along with metallic zinc were identified by XRD analysis.

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.

abstract = "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  - Copper from sulfate baths without and with added inorganic pigment particles based on strontium aluminate doped with europium and dysprosium (SrAl2O4: Eu2+, Dy3+) was electrodeposited on a brass cathode by a galvanostatic regime. Morphological, structural, and roughness analysis of the pigment particles, the pure (pigment-free) Cu coating, and the Cu coatings with incorporated pigment particles were performed using SEM, XRD, and AFM techniques, respectively. Hardness and creep resistance were considered for the examination of the mechanical properties of the Cu coatings, applying Chicot–Lesage (for hardness) and Sargent–Ashby (for creep resistance) mathematical models. The wettability of the Cu coatings was examined by the static sessile drop method by a measurement of the water contact angle. The incorporation of pigment particles in the Cu deposits did not significantly affect the morphology or texture of the coatings, while the roughness of the deposits rose with the rise in pigment particle concentrations. The hardness of the Cu coatings also increased with the increasing concentration of pigments and was greater than that obtained for the pigment-free Cu coating. The presence of the pigments caused a change in the wettability of the Cu coatings from hydrophilic (for the pigment-free Cu coating) to hydrophobic (for Cu coatings with incorporated particles) surface areas.

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  - 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.

Sn-Pd catalysts were prepared by two step electrodeposition technique whereby by regulating deposition conditions various forms of Sn dendrites and different atomic ratios of Sn:Pd were achieved. 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  - 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  - 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  - 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.

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.

abstract = "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.

AB  - Sn-Pd electrocatalysts convenient for a possible application in direct ethanol fuel cell were produced by two electrochemical deposition method. 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. Morpological and elemental analysis of the Sn-Pd electrocatalysts was performed by scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS), respectively. The particle size distribution (PSD) was used to estimate a size of Sn dendrites.

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  - 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.

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
