Oxidation of formaldehyde and ethanol on Au(1 1 1) and Au(1 1 1) modified by spontaneously deposited Ru in sulfuric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The oxidation of formaldehyde and ethanol on both pure Au(1 1 1) and Au(1 1 1) modified by approximately 0.3 monolayer (ML) of spontaneously deposited Ru was studied by cyclic voltammetry (CV) in 0.5 M H2SO4 solution ...
The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
The effect of pH on oxygen and hydrogen peroxide reduction on polycrystalline Pt electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Oxygen reduction (ORR) and hydrogen peroxide reduction (HPRR) reactions were studied on polycrystalline Pt by the rotating disc electrode technique in sulphate solutions over the entire pH range. Initial potentials for ...
HCOOH oxidation on thin Pd layers on Au: Self-poisoning by the subsequent reaction of the reaction product
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
The oxidation of HCOOH has been investigated on thin Pd layers ranging from 1 to 17 ML equivalents electrodeposited on polycrystalline Au substrate (Pd"Au). The results are compared to those on Pd black. Potentiodynamic ...
Electrodeposition and morphology of Ni, Co and Ni–Co alloy powders Part II. Ammonium chloride supporting electrolyte
(Elsevier, 2007)
Polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium chloride containing supporting electrolyte and their morphologies are investigated as a function ...
The electrochemical behavior of erythromycin A on a gold electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
The properties of carbon-supported hydrous ruthenium oxide obtained from RuOxHy sol
(Elsevier, 2003)
Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000® (BP) and Vulcan® XC-72 R (XC) were used as supporting materials. ...
Catalysis of hydrogen evolution on different Pd/Au(111) nanostructures in alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Hydrogen evolution reaction (HER) was studied on Pd/Au(1 1 1) bimetallic surfaces in alkaline solution. Au(1 1 1) was modified by palladium nanoislands spontaneously deposited using PdSO4 center dot 2H(2)O and PdCl2 salts. ...
Electrochemical investigation of ionic liquid-derived porous carbon materials for supercapacitors: pseudocapacitance versus electrical double layer
(Elsevier, 2019)
This work shows the potential application of carbon materials prepared by three different ionic liquid-based methods, using 1-butyl-3-methylimidazolium methanesulfonate [bmim][MeSO3], for electrochemical supercapacitors. ...
