The influence of pH on reaction pathways for O2 reduction on the Au(100) face
(Elsevier, 1996)
Oxygen reduction on the Au(100) face was studied by the rotating disk-ring electrode technique in solutions of anions which adsorb strongly on gold (HSO4-/SO42- and/or OH-) over the entire pH range. The specific adsorption ...
Hydrogen evolution on platinum in the presence of lead, cadmium and thallium adatoms
(Pergamon Press, 1979)
Hydrogen evolution on rotating platinum electrode has been measured in the presence of Pb, Tl and Cd adatoms. At low coverages of these adatoms (θM < 0.5) the mechanism of H2 evolution is the same as that for Pt, giving ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
Oxidation of formaldehyde and ethanol on Au(1 1 1) and Au(1 1 1) modified by spontaneously deposited Ru in sulfuric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The oxidation of formaldehyde and ethanol on both pure Au(1 1 1) and Au(1 1 1) modified by approximately 0.3 monolayer (ML) of spontaneously deposited Ru was studied by cyclic voltammetry (CV) in 0.5 M H2SO4 solution ...
Acceleration of electrocatalytic reactions by pulsation of potential: Oxidation of formic acid on Pt and Pt/Pbads electrodes
(Pergamon Press, 1978)
Pulsating potential electrolysis has been applied to one typical electrocatalytic reaction ie, the oxidation of formic acid on platinum and platinum partially covered by lead adatoms electrodes. It has been found that much ...
Electrodeposition of Ni, Co and Ni–Co alloy powders
(Elsevier, 2006)
In this paper the polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium sulfate containing supporting electrolyte are investigated as a function of Ni ...
Investigation of active carbon for fuel-cell electrodes
(Elsevier, 1969)
The influence of grain size, mode of catalyst impregnation, and different surface treatments on the electrochemical activity of active carbon for hydrogen fuel-cell electrodes was studied. The experiments were done in a ...
Studies of the deposition of cadmium on foreign substrates
(Elsevier, 1977)
Cadmium deposition on nickel, lead, silver, gold and copper has been studied by the potential sweep and potentiostatic method with a simultaneous observation of the surface by optical microscopy. It was found that the ...
On the kinetics and mechanism of the Cd(II)/Cd(Hg) system in acid media
(Elsevier, 1977)
The kinetics and mechanism have been investigated in the Cd(II)/Cd(Hg) system in 2 M NaClO4 + 1 M HClO4, at 25 ± 0.5°C. The galvanostatic single-pulse method has been used. The value of double-layer capacity, exchange ...
