AB  - The Ag, Pd and AgPd alloys of different morphologies and compositions were electrodeposited onto Au
and glassy carbon (GC) disc electrodes from the solution containing 0.001 M PdCl2 þ 0.04 M AgCl þ 0.1 M
HCl þ 12 M LiCl under the conditions of non-stationary (RPM ¼ 0, samples AgPd1 and AgPd2) and
convective diffusion (RPM ¼ 1000, sample AgPd3). Electrodeposited alloy layers were characterized by
the  scanning  electron  microscopy  (SEM),  energy  dispersive  X-ray  spectroscopy  (EDS),  and  X-ray
photoelectron spectroscopy (XPS). Oxygen reduction reaction (ORR) was investigated on all coatings in
0.1 M NaOH solution saturated with oxygen. The j-E curves for the ORR were recorded by two proced-
ures: (1) samples were cycled with 5 mV s
 1
from open circuit potential (OCP) to  0.8 V for Ag and AgPd
alloys (or  0.6 V for pure Pd) and back; (2) samples were cycled with 5 mV s
 1
from open circuit po-
tential to 0.45 V (formation of Ag2O, in the case of Pd formation of PdO and PdO2), from 0.45 V to  0.60 V
and back to the OCP. Significant catalytic activity for the Ag and AgPd alloys was detected after cycling
electrodes in the potential region of Ag2O formation and reduction. Increase of the catalytic activity for
AgPd alloys was, for the first time in the literature, ascribed to the presence of a certain amount of Ag2O
which could not be completely reduced during the reverse sweep from 0.45 V to  0.6 V. Catalytic activity
of AgPd alloys was found to be closely related to the amount of non-reduced Ag2O (most probably in the
form of Ag-hydroxide). In the absence of such treatment, the catalytic activity for the ORR on electro-
deposited Ag and AgPd alloy coatings was not detected.

AB  - The electrochemical deposition of the Fe-Ni alloy powders from citrate-sulfate containing electrolytes of different Ni/Fe ions concentration ratios at pH 4.5 was examined by the polarization measurements. All polarization curves have a similar shape and are characterized by the presence of two inflection points. The first inflection point reflects the beginning of alloy deposition, while the second one (˜) corresponds to the moment when the cathode reaction becomes determined by the rate of hydrogen bubbles formation. The potentials of Fe-Ni alloys deposition at all investigated Ni/Fe ratios are more positive than those for pure metal powders deposition. As the Ni/Fe ratio decreases, the polarization curves are placed at slightly more positive potentials. The morphology of electrodeposited powder particles was investigated using scanning electron microscopy (SEM). A common characteristic of all Fe-Ni alloy powders is the presence of cone shaped cavities. Powder particles electrodeposited at the ratio Ni/Fe = 9/1 are mainly consisted of nodules of either very flat surface or rough surface, with well defined crystals detected only on a few particles. With the decrease of the Ni/Fe ratio, the presence of well defined crystals on the nodule surface becomes more pronounced. In the powder with the highest amount of Fe (Ni/Fe = 1/3), the whole surface of all particles is covered with crystals of different shapes.

Sve polarizacione krive imaju sličan oblik i okarakterisane su prisustvom dve prevojne tačke na dijagramu. Prva prevojna tačka odgovara početku taloženja Fe-Ni legure, dok druga predstavlja momenat kada ukupna elektrohemijska reakcija postaje kontrolisana brzinom formiranja mehurova vodonika. Potencijali taloženja Fe-Ni legura pri svim ispitivanim odnosima Ni/Fe pozitivniji su od potencijala taloženja čistih metala, pri čemu se sa smanjenjem odnosa Ni/Fe polarizacione krive pomeraju ka malo pozitivnijim vrednostima potencijala. Morfologija čestica prahova ispitivana je korišćenjem skenirajuće elektronske mikroskopije (SEM). Zajednička karakteristika svih prahova Fe-Ni legura je prisustvo šupljina konusnog oblika.

Sa smanjenjem odnosa Ni/Fe, prisustvo kristala na površini čvorića postaje sve izraženije, dok su kod praha sa najvećim sadržajem Fe (Ni/Fe = 1/3) na celoj površini čestica prisutni kristali različitog oblika.

AB  - Polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium chloride containing supporting electrolyte and their morphologies are investigated as a function of Ni2+ and Co2+ ions concentrations. It is found that the shape of the polarization curves in all cases is practically defined by the shape of the polarization curve for hydrogen evolution. It is shown that correct polarization curves, as well as the morphology of electrodeposited powders are sensitive to the ratio of Ni2+/Co2+ ions concentration. Characteristic feature of powder particles obtained from chloride containing electrolytes is the presence of cone-shaped cavities. In the case of Ni powder cauliflower and spongy type particles are detected, while Co powder contains only spongy type particles. In all cases of alloy powder formation anomalous type of co-deposition is detected.

AB  - The processes of adsorption of sulphate anions onto the (111) face of silver have been investigated by analysis of the cyclic voltammetry and potcntiostatic pulse results. It was shown, by fitting the experimentally recorded θ - E dependences, that the adsorption of anions follows Frumkin adsorption isotherm. The adsorbed structure was found to be less dense than expected for the dense packed anion monolayer and the process was characterized by high value of the interaction parameter and the Gibbs energy of adsorption (f = 16.5 and ΔGoads.θ→0 = - 64 kJ mol 1). From the slope of the Ep.a - log (c0) dependence it was concluded that complete charge transfer between the adsorbed anions and the silver substrate occurs. This is supported by the Ep.a - log v linear dependence in the region of high sweep rates (v > 10 V s 1) with rational value of line slope (≈ 60 mV dec 1) which is possible only if the complete charge transfer reaction occurs. The elcctrosorption process of sulphate anions was found to be complex electrochemical reaction, taking place through three steps. It was proposed that the rate-determining step is the second step, i.e., the electrochemical formation of (SO4)ads species.
AB  - Proučavan je proces adsorpcije sulfatnih anjona na (111) pljosni monokristala
srebra metodama ciklične voltametrije i potenciostatskih pulseva. Na osnovu eksperimentalno određenih q–E zavisnosti pokazano je da se na adsorpciju može primeniti Frumkinova adsorpciona izoterma. Nađeno je da je gustina adsorbovanog sloja
manja nego kada bi sloj bio maksimalno moguće gusto pakovan kao i da adsorpciju
karakterišu visoke vrednosti Frumkinovog parametra interakcije (f = 16,5) i Gibsove
energije adosrpcije (DGºads,q®0 = –64 kJ mol). Na osnovu nagiba zavisnosti Ep,a –log (c0)
zaključeno je da se pri elektrosorpciji odigrava i potpuna izmena naboja anjona sa
supstratom. Ovaj zaključak podržava dobijena linearna zavisnost Ep,a – log v u oblasti
velikih brzina promene potencijala (v>10 V s–1) sa racionalnom vrednošću nagiba (»60
mV dek–1), a koja se može dobiti samo pri odigravanju potpune razmene naboja. Utvrđeno
je da je elektrosorpcija sulfatnih anjona složena elektrohemijska reakcija koja se
odigrava u tri stupnja. Stupanj koji određuje brzinu ukupne reakcije je drugi stupanj,
elektrohemijsko stvaranje intermedijera (SO4)ads.

The elcctrosorption process of sulphate anions was found to be complex electrochemical reaction, taking place through three steps. It was proposed that the rate-determining step is the second step, i.e., the electrochemical formation of (SO4)ads species., Proučavan je proces adsorpcije sulfatnih anjona na (111) pljosni monokristala
srebra metodama ciklične voltametrije i potenciostatskih pulseva. Na osnovu eksperimentalno određenih q–E zavisnosti pokazano je da se na adsorpciju može primeniti Frumkinova adsorpciona izoterma. Nađeno je da je gustina adsorbovanog sloja
manja nego kada bi sloj bio maksimalno moguće gusto pakovan kao i da adsorpciju
karakterišu visoke vrednosti Frumkinovog parametra interakcije (f = 16,5) i Gibsove
energije adosrpcije (DGºads,q®0 = –64 kJ mol). Na osnovu nagiba zavisnosti Ep,a –log (c0)
zaključeno je da se pri elektrosorpciji odigrava i potpuna izmena naboja anjona sa
supstratom. Ovaj zaključak podržava dobijena linearna zavisnost Ep,a – log v u oblasti
velikih brzina promene potencijala (v>10 V s–1) sa racionalnom vrednošću nagiba (»60
mV dek–1), a koja se može dobiti samo pri odigravanju potpune razmene naboja. Utvrđeno
je da je elektrosorpcija sulfatnih anjona složena elektrohemijska reakcija koja se
odigrava u tri stupnja. Stupanj koji određuje brzinu ukupne reakcije je drugi stupanj,
elektrohemijsko stvaranje intermedijera (SO4)ads.",
