AB  - Polymer resins based on acrylates obtained from Bis-GMA (Bisphenol A glycide methacrylate), which is suitable for photopolymerization, are used in dentistry for various purposes due to the ease of application and the possibility to influence their properties by adding reinforcements of different shapes, crystal structure and chemical compositions. Reinforcement in the form of particles based on MgAlLDH (layered double hydroxide) deposited on silica obtained from rice husks on two substrates. A metal base and glass were used. The adhesive properties are important in order to see the possibility of using these materials in applications. In order to measure the adhesive properties of the material, the composite microhardness measurement method is used by applying different loads in order to evaluate the adhesion parameter that shows the effect of the coating on the substrate. It was compared to how a pure photopolymerizing acrylate matrix bonds with a chromium-based dental alloy substrate that is used in the production of different parts of dentures by bonding to a glass substrate. Then, it was compared how composite materials are bonded to both substrates. Adhesion was monitored through the change in wetting angle between the composites, and the results were compared with the results of microindentation. It was shown that the addition of composite particles increases the adhesive properties of the composite compared to the pure matrix and that better adhesion is achieved between the composite and the metal substrate than between the composite and the glass substrate.

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  - 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  - The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte
has been investigated. Morphology and structure of Sn dendrites produced applying both potentiostatic and galvanostatic regimes of the electrolysis are characterized by SEM and XRD, respectively. Depending on the applied cathodic potentials, three types of Sn dendrites were obtained: (a) needle like and spear-like, (b) fern-like, and (c) stem-like dendrites. The very branchy dendrites with branches of the prismatic shape obtained by the galvanostatic regime of electrolysis represented a
novel type of Sn dendrites, not previously reported in the literature. To explain the formation of
various dendritic forms, correlation with the polarization characteristics for this electrodeposition
system is considered. The needle-like and the spear-like dendrites represented monocrystals of
(200),(400) preferred orientation, the fern-like dendrites exhibited the predominant (220),(440) preferred
orientation, while in the stem-like particles Sn crystallites were oriented to a greater extent in
the (440) crystal plane than in other planes. The galvanostatically synthesized Sn particles possessed the strong (200),(400) preferred orientation. The strong influence of parameters and regimes of
electrodeposition on structural characteristics of Sn dendrites is explained by the fundamental laws
of electrocrystallization taking into consideration the concept of slow-growing and fast-growing
crystal planes.

AB  - Comparative analysis of morphological and structural features of copper dendrites obtained by potentiostatic and galvanostatic regimes of electrolysis was made. The 3D (three dimensional) pine-like dendrites composed from stalk and corncob-like forms as branches, with the sharp tips of both stalk and branches, were obtained by the potentiostatic regime of electrolysis with all analyzed amounts of passed electricity. On the other hand, with increasing the amount of the passed electricity the shape of 3D pine-line dendrites obtained by the galvanostatic regime of electrolysis changed than those with the sharp tips of stalk and branches to those which the tips finished globules. Comparing with Cu deposits obtained at overpotentials which belonged to different types of electrodeposition control, it is concluded that overpotential at the end of passed amount of the electricity plays crucial role in the final shape of galvanostatically produced Cu dendrites. Irrespective of the shape of Cu dendrites, crystallites of copper were random oriented in the both types of dendrites.
AB  - Napravljena je uporedna analiza morfoloških i strukturnih karakteristika dendrita bakra dobijenih potenciostatskim i galvanostatskim režimima elektrolize. Trodimenzionalni (3D) dendriti nalik stablu bora izgrađeni od stabla i grana koje nalikuju klipovima kukuruza, sa oštrim vrhovima, su bili dobijeni potenciostatskim režimom elektrolize sa svim analiziranim količinama propuštenog naelektrisanja. Na drugoj strani, sa povećanjem količine propuštenog naelektrisanja oblik 3D dendrita dobijenih galvanostatskim režimom elektrolize se menjao od onih sa oštrim vrhovima i stalka i grana do onih čiji vrhovi su se završavali globulama. Poređenjem sa talozima bakra dobijenim na prenapetostima koje su pripadale različitim tipovima kontrole procesa elektrohemijskog taloženja, zaključeno je da prenapetost na kraju propuštene količine naelektrisanja igra presudnu ulogu u krajnjem obliku galvanostatski proizvedenih Cu dendrita. Bez obzira na oblik Cu dendrita, kristaliti bakra su bili slučajno orijentisani u oba tipa dendrita.

AB  - Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been
investigated. Morphological and structural characteristics of this electrode type obtained by various parameters of RC regimes
were examined by the techniques of scanning electron and optical microscopies, while the amount of hydrogen produced during
electrodeposition process was quantified by determination of the average current efficiency for hydrogen evolution reaction. To
optimize the process of formation of the honeycomb-like electrodes, the following parameters of square wave RC regimes were
analyzed: the cathodic current density, the same anodic to cathodic time ratios but various durations of the cathodic and the
anodic pulses, and the various values of the anodic to cathodic time ratios. The minimal amount of hydrogen spent for formation
of the honeycomb-like electrodes with maximal number of holes formed from detached hydrogen bubbles is obtained with the
anodic to cathodic time ratio of 0.50 and duration of the cathodic and anodic pulses of 2 and 1 s, respectively. To explain
formation of the honeycomb-like electrodes of optimal morphological and structural characteristics, the upgraded mathematical
model defining the RC regime in the second range was proposed and discussed.

AB  - The morphologies of copper dendritic forms obtained in both potentiostatic and galvanostatic regimes of electrolysis with various amounts of the electricity were analyzed by the scanning electron microscopy (SEM) technique. Irrespective of amount of passed electricity, 3D (three dimensional) pine-like dendrites with sharp tips were formed in the potentiostatic regime of electrolysis. On the other hand, the amount of passed electricity had a strong effect on the shape of the 3D pine-like dendrites formed in the galvanostatic regime of electrolysis. Dendrites with sharp tips were formed with smaller amount of passed electricity, while dendrites with globular tips were formed with larger amounts. The change in the shape of the galvanostatically synthesized 3D pine-like dendrites was explained by comparison with copper deposits obtained potentiostatically at overpotentials that corresponded to the final overpotentials during galvanostatic regime of electrolysis for the analyzed amounts of electricity. Based on the similarity of the obtained morphologies at the macro level, it was concluded that the overpotential plays a crucial role in the formation of the electrolytically synthesized dendrites and that the controlled conditions of electrolysis could represent a suitable way for a synthesis of spherical Cu particles by electrolysis.

AB  - Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution reaction and by scanning electron (SEM) and optical (OM) microscopic analysis of the obtained deposits. Keeping the cathodic current density, the cathodic and the anodic pulses constant in all experiments, the anodic current density (ja) values were varied: 40, 80, 160, 240 and 320 mA cm−2. The Cu deposits produced by the RC regimes with different anodic current density values were compared with that obtained in a constant galvanostatic regime (DC) at the current density equal to the cathodic current density in the RC regimes. The honeycomb-like structures were formed in the DC regime and by the RC regimes with ja of 40 and 80 mA cm−2. The hole size in them was in the 60–70 μm range. Due to the decrease of quantity of evolved hydrogen with increasing anodic current density, the larger dish-like holes with dendrites at their bottom and shoulder were formed with ja values of 160, 240 and 320 mA cm−2. The maximum number of holes, and hence, the largest specific surface area of the honeycomb-like electrodes was obtained with ja = 80 mA cm−2, that can be ascribed to a suppression of coalescence of neighboring hydrogen bubbles. Application of the RC regime also led to the increase of uniformity of structures, what is concluded by cross section analysis of the formed honeycomb-like electrodes. For the first time, mechanism of Cu electrodeposition in the hydrogen co-deposition range by the RC regime in the second range was proposed and discussed.

AB  - Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution reaction and by scanning electron (SEM) and optical (OM) microscopic analysis of the obtained deposits. Keeping the cathodic current density, the cathodic and the anodic pulses constant in all experiments, the anodic current density (ja) values were varied: 40, 80, 160, 240 and 320 mA cm−2. The Cu deposits produced by the RC regimes with different anodic current density values were compared with that obtained in a constant galvanostatic regime (DC) at the current density equal to the cathodic current density in the RC regimes. The honeycomb-like structures were formed in the DC regime and by the RC regimes with ja of 40 and 80 mA cm−2. The hole size in them was in the 60–70 μm range. Due to the decrease of quantity of evolved hydrogen with increasing anodic current density, the larger dish-like holes with dendrites at their bottom and shoulder were formed with ja values of 160, 240 and 320 mA cm−2. The maximum number of holes, and hence, the largest specific surface area of the honeycomb-like electrodes was obtained with ja = 80 mA cm−2, that can be ascribed to a suppression of coalescence of neighboring hydrogen bubbles. Application of the RC regime also led to the increase of uniformity of structures, what is concluded by cross section analysis of the formed honeycomb-like electrodes. For the first time, mechanism of Cu electrodeposition in the hydrogen co-deposition range by the RC regime in the second range was proposed and discussed.

AB  - Lead and nickel powder particles were produced by the processes of electrolysis and characterized by scanning electron microscope (SEM). The X-ray diffraction (XRD) analysis of the produced particles was done. Morphologies of Pb and Ni particles were correlated with their crystal structure at the semi quantitative level by determination of 'Texture Coefficients' (TC) and 'Relative Texture Coefficient' (RTC). The two dimensional (2D) dendritic particles of lead of different degree of ramification were obtained by the potentiostatic regime of electrolysis from the nitrate, acetate and hydroxide electrolyte. The spongy-like particles of nickel constructed from holes formed of the detached hydrogen bubbles and surrounded by cauliflower-like agglomerates of approximately spherical grains (the honeycomb-like structure) were obtained by the galvanostatic regime of electrolysis from the chloride electrolyte. Although crystallites were dominantly oriented in the (111) plane in both Pb and Ni particles, analysis of the XRD data showed different preferred orientation of the formed particles. All types of Pb dendritic particles showed the strong (111) preferred orientation, while crystallites of Ni in the spongy-like particles were almost random oriented. The obtained results were discussed following Winand's classification of metals on the normal, intermediate and inert metals based on their values of the exchange current density, melting point and overpotential for hydrogen evolution reaction.

AB  - The processes of lead and zinc electrodeposition from the very dilute electrolytes were compared by the analysis of polarization characteristics and by the scanning electron microscopic (SEM) analysis of the morphology of the deposits obtained in the galvanostatic regime of electrolysis. The exchange current densities for lead and zinc were estimated by comparison of experimentally obtained polarization curves with the simulated ones obtained for the different the exchange current density to the limiting diffusion current density ratios. Using this way for the estimation of the exchange current density, it is shown that the exchange current density for Pb was more than 1300 times higher than the one for Zn. In this way, it is confirmed that the Pb electrodeposition processes are considerably faster than the Zn electrodeposition processes. The difference in the rate of electrochemical processes was confirmed by a comparison of morphologies of lead and zinc deposits obtained at current densities which corresponded to 0.25 and 0.50 values of the limiting diffusion current densities.

AB  - In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA cm(-2) were determined using new method based on comparison of experimental and simulated polarization curves, and the excellent agreement with the values found in the literature has been attained. Correlation between the polarization characteristics and morphologies of zinc deposits characterized by the scanning electron microscopic (SEM) technique was established. The spongy-like particles constructed from nanofilaments and the large grains or boulders were formed in the zone of the fast increase of the current density with the overpotential before the plateau of the limiting diffusion current density was reached. The shape of dendrites, formed inside the plateau of the limiting diffusion current density and at the higher ones, strongly depended on overpotential of the electrodeposition. Mechanism of formation of all obtained forms was discussed by the consideration of the different rates of growth of surface protrusions in a function of the overpotential of electrodeposition through the analysis of the change of the ratio between the height and the radius of the protrusions. In order to confirm of the proposed mechanism, comparison with polarization and morphological characteristics of the other metals characterized by the different exchange current density values was made and discussed. Although zinc is classified in the group of the normal metals characterized by the high values of the exchange current density, it was found that the polarization and morphological characteristics of zinc show certain and strong similarities with those of copper, classifying zinc just at boundary between the normal and intermediate metals, that is confirmed by the estimation of the exchange current density value for zinc.

Although zinc is classified in the group of the normal metals characterized by the high values of the exchange current density, it was found that the polarization and morphological characteristics of zinc show certain and strong similarities with those of copper, classifying zinc just at boundary between the normal and intermediate metals, that is confirmed by the estimation of the exchange current density value for zinc.",

Diagnostic criteria based on the j(0)/j(L) ratios were established. For j(0)/j(L) > 100, the system is under the ohmic control. In the range 1  LT  j(0)/j(L)  LT = 100, there is mixed ohmic-diffusion control. Pure diffusion control appears in the range 0.1  LT  j(0)/j(L)  LT = 1. For j(0)/j(L)  LT = 0.1, the system is activation controlled at low overpotentials. The proposed diagnostic criteria were verified by comparison of the simulated curves with experimentally recorded ones and by morphological analysis of deposits obtained under the different types of control of the metal electrodeposition process.

AB  - The one of the main contributions of Belgrade Electrochemical School to the field of metal electrodeposition is investigation of a mechanism of formation and growth of the disperse deposits. Spongy-like, cauliflower-like, needle-like, carrot-like, dendrites of various shapes, etc. are the typical disperse forms obtained by the electrodeposition processes. From the electrochemical point of view, a dendrite, as the most significant disperse form, is defined as an electrode surface protrusion that grow under activation or mixed control, while deposition to the flat part of the electrode surface is under complete diffusion control. In this paper, all electrochemical aspects concerning mechanism of formation and growth of dendrites are reviewed.

AB  - The processes of lead electrodeposition from electrolytes of various concentrations of sodium nitrate as the supporting electrolyte have been examined by chronoamperometry and by the scanning electron microscopic (SEM) analysis of deposits obtained in the potentiostatic regime of electrolysis. The good agreement between the diffusion coefficents determined by Cottrell equation and non-linear fitting method was observed. For the first time, the transition from the mixed ohmic-diffusion to the full diffusion control was defined from the analysis of Cottrell equation. The parameters, such as the number density of active sites and the nucleation rate constant, obtained by non-linear fitting method were discussed in accordance with the fact that lead belongs to the group of metals characterized by the high values of the exchange current density. The data obtained by the chronoamperometric analysis were succesfully correlated with morphologies of electrodeposited lead obtained in the different types of electrodeposition control.

AB  - Electrodeposition of lead from the concentrated nitrate electrolyte in the potentiostatic regime of electrolysis has been investigated by the analysis of the potentiostatic current transients and scanning electron microscope (SEM). It was found that the process of Pb nucleation from the concentrated electrolyte follows Scharifker model based on the 3D (three-dimensional) instantaneous nucleation with diffusion-controlled growth. The deviations of the obtained dependencies from the theoretical prediction for this model have been also discussed. Needle-like and fern-like dendrites, as well as crystals of irregular shape (precursors of dendrites) were formed in the diffusion controlled electrodeposition. The SEM analysis of these dendritic forms revealed their 2D (two-dimensional) growth. The size of needle-like dendrites was considerably larger than the size of both the fern-like dendrites and the irregular crystals. Although the electrodeposition process occurred inside the linear diffusion layer of the macroelectrode, the shape and size of dendrites were determined by the effect of local diffusion fields formed around tips (spherical diffusion) and top edges (cylindrical diffusion) of protrusions formed in the initial stage of the electrodeposition. The growth rates under the conditions of spherical and cylindrical diffusion control were mutually compared and a faster growth under the conditions of the spherical, in relation to the cylindrical diffusion, was proved. The effect of the current density distribution on formation of the final forms of Pb dendrites was also discussed.

AB  - The polarization and morphological characteristics of powder forms of the group of the intermediate metals were examined by the analysis of silver and copper electrodeposition processes at high overpotentials. The pine-like dendrites constructed from the corncob-like forms, which are very similar to each other, were obtained by electrodeposition of these metals at the overpotential belonging to the plateaus of the limiting diffusion current density. A completely different situation was observed by the electrodeposition of silver and copper at the overpotential outside the plateaus of the limiting diffusion current density in the zone with the fast increase in current density with the overpotential. Silver dendrites, which were very similar to silver and copper dendrites obtained inside the plateaus of the limiting diffusion current density, were obtained at the overpotential outside the plateau. Due to the lower overpotential for hydrogen evolution for copper, hydrogen produced during the copper electrodeposition process strongly affected the surface morphology of copper. The same shape polarization curves with completely different surface morphologies of Cu and Ag electrodeposited at overpotentials after the inflection point clearly indicate the importance of morphological analysis in the investigation of polarization characteristics of the electrodeposition systems. The role of hydrogen as a crucial parameter in the continuous change of copper surface morphology from dendrites to honeycomb-like structures was investigated in detail. On the basis of this analysis, the transitional character of the intermediate metals between the normal and inert metals was considered. The typical powder forms characterising electrodeposition of the intermediate metals were also defined and systematized.

AB  - Lead electrodeposition processes from basic (nitrate) and complex (acetate) electrolytes were mutually compared by scanning electron microscopy and X-ray diffraction investigation of the produced powder particles. The shape of dendritic particles strongly depended on the type of electrolyte. Dendrites composed of a stalk and weakly developed primary branches (the primary type) were predominantly formed from the basic electrolyte. Ramified dendrites composed of a stalk and of both primary and secondary branches (the secondary type) were mainly formed from the complex electrolyte. In both types of powder particles, Pb crystallites were predominantly oriented in the (111) plane. The formation of powder particles of different shapes with strong (111) preferred orientation is discussed and explained by consideration of the general characteristics of the growth of crystals in electrocrystallization processes.
AB  - Procesi elektrohemijskog taloženja olova iz osnovnog (nitratnog) i kompleksnog (acetatnog) elektrolita su bili međusobno upoređeni tehnikom skenirajuće elektronske mikroskopije i rendgensko-difrakcionom analizom proizvedenih čestica praha. Oblik dendritičnih čestica je snažno zavisio od tipa elektrolita. Dendriti sastavljeni od stabla i slabo razvijenih grana (primarni tip) su bili predominantno formirani iz osnovnog elektrolita. Razgranati dendriti sastavljeni od stabla i od primarnih i sekundarnih grana (sekundarni tip) su bili uglavnom formirani iz kompleksnog elektrolita. U oba tipa praškastih čestica kristaliti olova su bili dominantno orijentisani u (111) ravni. Formiranje praškastih čestica sa strogom (111) orijentacijom je bilo diskutovano i objašnjeno razmatranjem opštih karakteristika rasta kristala u procesima elektrokristalizacije.

In both types of powder particles, Pb crystallites were predominantly oriented in the (111) plane. The formation of powder particles of different shapes with strong (111) preferred orientation is discussed and explained by consideration of the general characteristics of the growth of crystals in electrocrystallization processes., Procesi elektrohemijskog taloženja olova iz osnovnog (nitratnog) i kompleksnog (acetatnog) elektrolita su bili međusobno upoređeni tehnikom skenirajuće elektronske mikroskopije i rendgensko-difrakcionom analizom proizvedenih čestica praha. Oblik dendritičnih čestica je snažno zavisio od tipa elektrolita. Dendriti sastavljeni od stabla i slabo razvijenih grana (primarni tip) su bili predominantno formirani iz osnovnog elektrolita. Razgranati dendriti sastavljeni od stabla i od primarnih i sekundarnih grana (sekundarni tip) su bili uglavnom formirani iz kompleksnog elektrolita. U oba tipa praškastih čestica kristaliti olova su bili dominantno orijentisani u (111) ravni. Formiranje praškastih čestica sa strogom (111) orijentacijom je bilo diskutovano i objašnjeno razmatranjem opštih karakteristika rasta kristala u procesima elektrokristalizacije.",

AB  - A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology of the lead deposits obtained in the potentiostatic regime of electrolysis. In dependence on the concentration of Pb(II) ions, the electrodeposition process is either mixed ohmic-diffusion or completely ohmic controlled. The ratio of the ohmic control to the total control of the electrodeposition process increased with increasing concentration of Pb(II) ions and at the higher concentrations of Pb(II) ions, the electrodeposition process became completely ohmic controlled. The polarization characteristics were well correlated with the morphologies of the obtained lead deposits. The formation of regular crystals was a characteristic of ohmic control of the electrodeposition process, while needle-like and fern-like dendrites were the predominant morphological forms obtained under diffusion control. The critical overpotentials for both dendritic growth initiation and instantaneous dendritic growth were analyzed and a mechanism of lead electrodeposition based on this analysis is presented. It was shown that the values of these critical overpotentials decreased and approached one another with increasing concentration of Pb(II) ions and finally became the same when full ohmic control was attained. The presented results were in good agreement with the predications of the general theory for the formation of disperse metal electrodeposits.

AB  - The processes of lead electrodeposition from the basic (nitrate) and complex (acetate) electrolytes were mutually compared by the analysis of their polarization characteristics and by the scanning electron microscopic (SEM) analysis of the morphology of formed deposits. Although the polarization characteristics of lead recorded from these two electrolytes were relatively similar to each other, the shape of formed dendrites strongly depended on the type of electrolyte. The dendrites composed of stalk and weak developed primary branches (the primary (P) type) were predominantly formed from the basic electrolyte. On the other hand, the very branchy dendrites composed of stalk and of both primary and secondary branches (the secondary (S) type) were mainly electrodeposited from the complex electrolyte. Considering the fact that the application of lead powder in many technologies is closely related with its surface morphology, the special attention was given to the analysis of the type of electrolytes on formation of the different dendritic forms. It was shown that formation of more branchy dendrites from the acetate electrolyte can be ascribed to the lower exchange current density (or to the lower rate of electrochemical process) for this electrolyte than for the nitrate one due to the process of complex formation.

AB  - In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition times were examined using the technique of scanning electron microscopy (SEM). The different disperse morphological forms, such as granules, needle-like and spongy-dendritic ones were formed during silver electrodeposition from this solution. The size of granules decreased and their number increased with the increase of overpotential of electrodeposition. With the increasing overpotential, the induction time for the appearance of spongy-dendritic forms decreased with a tendency to increase their ramification. Mathematic model describing the mechanism of metal electrodeposition at the high overpotentials is proposed and discussed on the basis of the obtained silver surface morphology.

AB  - Electrodeposition and electroless deposition of metallic powders were comparatively investigated. Electrodeposition of copper is accompanied with the simultaneous hydrogen evolution, which significantly influences the morphology of Cu powder. At lower overpotentials, branched dendrites were produced. At higher overpotentials honeycomb-like deposits of copper were obtained. Formation of silver powders was characterized by the comparison of the exchange and limiting current densities. Instantaneous growth of dendrites starts at low overpotential due to large exchange current density in silver nitrate solution. Formation of powders such as Ni, Co, Ag, Pd and Au from homogenous solutions using an appropriate reducing agent or via galvanic displacement reaction was demonstrated. The hydrolysis of metallic ions is crucial in the deposition metallic powders via electroless deposition from homogenous solutions. Oxides, such as Ag 2O, Cu 2O and CuO, suspended in water can successfully be reduced with an appropriate reducing agent, leading to the precipitation of metallic powders.
