Optical and electrochemical study of electrocatalysis by foreign metal adatoms. Oxidation of formic acid on rhodium
(Elsevier Sequoia S.A., 1979)
Specular reflectance spectroscopy, in conjunction with linear potential sweep voltammetry, has been used in studying catalytic effects of Pb and Cd adatoms on the oxidation of HCOOH on Rh. The intermediates formed in that ...
A New Approach to Metal Electrodeposition at a Periodically Change Rate. Part I. The Reversing Overpotential Method
(Elsevier, 1999)
A method of increasing the apparent deposition exchange current density value in reversing overpotential (RO) copper electrodeposition is described. In pulsating overpotential (PO) metal electrodeposition, the current ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier, 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticles (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Investigation of the anodic processes on platinum in perchlorate and chlorate solutions by linear sweep voltammetry using the rotating double-ring electrodes
(Elsevier, 1976)
There have been several attempts to elucidate events occurring on platinum immersed into pure perchloric acid solutions, when submitted to high anodic polarisation. The polarisation curve was shown to exhibit two levels, ...
Kinetic and mechanistic study of methanol oxidation on a Pt 100/ surface in alkaline media
(Elsevier, 1998)
A comparative study of methanol oxidation on a Pt(100) surface was carried out in bicarbonate, carbonate and different pH values of sodium hydroxide solutions. It was shown that Pt(100) adsorbs OH and 'poisoning species'. ...
The influence of OH- chemisorption on the catalytic properties of gold single crystal surfaces for oxygen reduction in alkaline solutions
(Elsevier, 1996)
Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical ...
Electrocatalysis by foreign metal monolayers: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was demonstrated that some foreign metal monolayers formed by underpotential deposition have pronounced catalytic effects on the oxidation of formic acid on platinum. The explanation of these effects was sought within ...
Structural effects in electrocatalysis. Oxygen reduction on the Au (100) single crystal electrode
(Elsevier, 1984)
The kinetics of O2 reduction on the Au (100) single crystal electrode have been examined in alkaline electrolytes using the rotating dise method. A comparison has been made with the Au (110) and Au (111) surfaces. The ...
The effect of hydrogen codeposition on the morphology of copper electrodeposits. 1. The concept of effective overpotential
(Elsevier, 2006)
The effect of hydrogen codeposition on the morphology of copper electrodeposits was studied. The dependences of the overall current and the volume of evolved hydrogen on the quantity of electricity used were plotted and ...
On the deactivation mechanism of RuO2–TiO2/Ti anodes prepared by the sol–gel procedure
(Elsevier, 2005)
The deactivation process that leads to the end of titanium supported RuO2-TiO2 coating service life, for anodes prepared from RuO2 and TiO2 sols, as well as by the conventional thermal decomposition of RuCl3 and TiCl3, was ...
