The effect of anions on the electrochemical behaviour of aluminium
(Elsevier, 1983)
Aluminum has been known to exhibit widely different electrochemical properties in different aqueous electrolytes. Thus, OH- ions in strongly alkaline solutions reveal its strong affinity to water by dissolving its protective ...
Oxygen reduction reaction on spontaneously and potentiodynamically formed Au/TiO2 composite surfaces
(Elsevier, 2007)
From aqueous solutions, gold was deposited on freshly polished titanium surface either by displacement reaction or by potentiodynamic polarization. Both of these procedures resulted in the formation of Au/TiO2 composite ...
Investigation of active carbon for fuel-cell electrodes
(Elsevier, 1969)
The influence of grain size, mode of catalyst impregnation, and different surface treatments on the electrochemical activity of active carbon for hydrogen fuel-cell electrodes was studied. The experiments were done in a ...
Electrochemical deposition and characterization of Zn /Co alloys and corrosion protection by electrodeposited epoxy coating on Zn /Co alloy
(Elsevier, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Hydrogen Evolution Reaction on Platinum Catalyzed by Palladium and Rhodium Nanoislands
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Pd/Pt(poly) and Rh/Pt(poly) bimetallic electrodes prepared by spontaneous deposition of Pd and Rh nanoislands on Pt(poly) at submonolayer coverage were explored as catalysts for hydrogen evolution reaction (HER) in alkaline ...
Characterization and electrochemical properties of organomodified and corresponding derived carbonized clay
(Oxford : Pergamon-Elsevier Science Ltd, 2019)
Series of alkylammonium modified smectites with different alkylammoinum/clay ratios was synthesized (H series). The obtained organoclays were used as precursors for carbon-clay composite materials (C series). Both set of ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt"Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
Optical and electrochemical study of cation adsorption on oxide layers on gold and platinum electrodes
(Elsevier, 1985)
It has been shown that the adsorption of Bi3+ and Tl+ cations occurs on oxide layers of Au and Pt electrodes in acid solutions. The initial stages of oxide formation and reduction are inhibited. The effect increases with ...
Mechanically activated carbonized rayon fibers as an electrochemical supercapacitor in aqueous solutions
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
The activated carbon cloth (ACC), obtained by chemical/physical activation of carbonized rayon fibers, was grinded in a ball mill and studied from the aspect of double layer capacitance. The changes in pore structure, ...
