Fundamental aspects of pulsating current metal electrodeposition IX: The prevention of spongy deposit formation on inert substrates
(Elsevier, 1984)
It is shown that spongy deposits are obtained under d.c. conditions and that compact deposits are obtained in pulsating current (PC) deposition with high pause-to-pulse ratios at the same average current density and ...
Structural effects in electrocatalysis: Oxygen and hydrogen peroxide reduction on single crystal gold electrodes and the effects of lead ad-atoms
(Elsevier, 1982)
Structural effects in electrocatalysis have been clearly and definitely demonstrated for example in the oxidation of HCOOH, CH3OH and CH2O on platinum single crystal electrodes. In this note, we report considerable structural ...
Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
The critical overpotential for zinc dendrite formation
(Kluwer Academic Publishers, 1979)
The critical overpotential for zinc dendrite growth is determined as 173 mV by the method described by Popov et al. [1]. It was shown that this procedure can be applied successfully to metal deposition processes when there ...
Electrochemical oxidation of formic acid at noble metals: Catalytic effects of foreign metal monolayers
(Elsevier, 1977)
The catalytic effects of a submonolayer of lead on noble metals have been shown and discussed in terms of a previously published model. A theoretical analysis of these effects is presented. It was demonstrated that foreign ...
Oscillatory phenomena in oxygen and hydrogen peroxide reduction on the Au(100) electrode surface in alkaline solutions
(Elsevier, 1992)
In this work we report preliminary data for oscillatory behavior found in oxygen and hydrogen peroxide reduction on a rotating gold electrode with (100) orientation in alkaline solutions.
Nanoscale pattern formation during electrodeposition: Ru on reconstructed au(111)
(USA : American Physical Society, 1999)
Scanning tunneling microscopy results on Ru electrodeposition on reconstructed Au(111) are presented, which show a novel type of site-selective nucleation on this surface. At potentials around 0.0 V vs the Ag/AgCl reference ...
Oxygen reduction on the Au (311) electrode surface in alkaline electrolyte
(Elsevier, 1988)
Oxygen reduction was studied for the first time using a single crystal electrode in a rotating disc-ring arrangement. The Au (311) surface shows a complex behaviour, with a very high activity in certain potential regions. ...
Surface properties of RuO2 + IrO2 mixed oxide electrodes
(Elsevier, 1986)
The surface properties of RuO2 + IrO2 mixed oxide layers deposited on Ti by thermal decomposition of the corresponding chlorides in aqueous solutions have been investigated by means of cyclic voltammetry and ex situ UHV ...
Structural effects in electrocatalysis: oxidation of formic acid and hydrogen adsorption on platinum single-crystal stepped surfaces
(Elsevier, 1986)
The oxidation of formic acid and hydrogen adsorption have been measured on platinum single-crystal stepped surfaces with five orientations. A pronounced structural sensitivity of both reactions has been found. They show a ...
