On the deactivation mechanism of RuO2-TiO2/Ti anodes prepared by the sol-gel procedure
(Elsevier Science Sa, Lausanne, 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 ...
Adsorption of oxygen containing species and their effect on oxygen reduction on Pt3Co electrode
(Elsevier Science Sa, Lausanne, 2003)
A rotating Pt3Co, thermally prepared alloy disc is used to study electrochemical oxygen reduction in alkaline solutions of different pH. In all solutions two Tafel regions are found: at low current densities partial ...
Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
The influence of cobalt loading on electrocatalytic performance toward glucose oxidation of pillared montmorillonite-supported cobalt
(Elsevier B.V., 2022)
In this paper, the influence of cobalt loading in pillared clay-supported cobalt materials on their electrocatalytic performance toward glucose oxidation was investigated. A series of aluminum-pillared montmorillonite clay ...
Oxygen reduction reaction on Pt(111): effects of bromide
(Elsevier Science Sa, Lausanne, 1999)
Using the rotating ring-disk technique (RRDE) the oxygen reduction reaction (orr) was studied on the Pt(111) surface in the presence of Br- anions. We found that the orr at the Pt(111) \ Br-ad interface is always accompanied ...
The potentiostatic current transients and the role of local diffusion fields in formation of the 2D lead dendrites from the concentrated electrolyte
(Elsevier, 2015)
Electrodeposition of lead from the concentrated nitrate electrolyte in the potentiostatic regime of electrolysis has been investigated by the analysis of the potentiostatic current transients and scanning electron microscope ...
Rate expression for electrochemical oxidation of methanol on a direct methanol fuel cell anode
(Elsevier, 2005)
The kinetics of methanol oxidation at PtRu catalyst was investigated on a membrane electrode assembly (MEA) in a cyclone flow cell. Catalyst characterisation was done by means of cyclic voltammetry and CO stripping. The ...
On the kinetics of the hydrogen evolution reaction on nickel in alkaline solution - Part II. Effect of temperature
(Elsevier S.A., 2001)
The effect of temperature on the kinetics of the hydrogen evolution reaction (her) on nickel in 1.0 mol dm (-3) NaOH solution was studied. In this article, four sets of experiments were done in a non-isothermal cell. In ...
Oscillatory behavior in the electrochemical oxidation of formic acid on Pt(100): rotation and temperature effects
(Elsevier Science Sa, Lausanne, 2001)
We investigated the oscillatory behavior in the kinetics of formic acid electrooxidation on Pt(100) in 1 mM HClO4 solution. We studied the effect of different experimental parameters on the oscillatory behavior, viz. defined ...
