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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
