The effect of rhodium nanoislands on the electrocatalytic activity of gold for oxygen reduction in perchloric acid solution
(Elsevier, 2013)
The effect of spontaneously deposited rhodium nanoislands on the electrocatalytic activity of polycrystalline gold, Au(poly), for oxygen reduction reaction (ORR) was studied using rotating disc electrode technique in 0.1 ...
Catalysis of oxygen reduction on electrochemically activated polycrystalline gold by Pd nanoislands in alkaline solution
(Elsevier, 2017)
Catalytic properties of electrochemically activated polycrystalline gold, Au(poly), modified by spontaneously deposited palladium nanoislands with the coverage below a monolayer were examined for the oxygen reduction ...
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 ...
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 ...
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, ...
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 ...
Oxide formation on gold single crystal stepped surfaces
(Elsevier, 1988)
Oxide formation and anion adsorption have been studied on gold single crystal stepped surfaces. Most of the measurements were performed in sulphuric and some in perchloric acid solutions by cyclic voltammetry and by double ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
