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 ...
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 ...
An electrochemical illustration of the mathematical modelling of chlorine impact and acidification in electrochemical tumour treatment and its application on an agar-agar gel system
(Elsevier, 2003)
Electrochemical treatment (EchT) of tumours, which is also known as electrochemical therapy, implies that tumour tissue is treated with a direct current through the use of electrodes. This was shown earlier when the major ...
Capacitive properties of RuO2-coated titanium electrodes prepared by the alkoxide ink procedure
(Elsevier Science Sa, Lausanne, 2007)
The capacitive properties of titanium electrodes with an active porous RuO2 coating were investigated in H2SO4 and NaCl solution by cyclic voltammetry and electrochemical impedance spectroscopy. Electrodes with two different ...
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 ...
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 ...
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 ...
Nb-doped TiO2 as a support of Pt and Pt-Ru anode catalyst for PEMFCs
(Elsevier Science Sa, Lausanne, 2010)
TiO2 doped by 0.5% Nb was synthesized by the acid-catalyzed sol-gel method. BET surface area was determined to be 72 m(2) g(-1). XRD measurements showed that TiO2 has structure of anatase with similar to 13 nm average ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier Science Sa, Lausanne, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
