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, ...
Carbon monoxide oxidation on Au(111) surface decorated by spontaneously deposited Pt
(Elsevier, 2007)
Platinum is deposited spontaneously on Au(1 1 1) surface from 1 mM H2PtCl6 + 1 M HClO4 solution using multiple deposition procedure. X-ray photoelectron spectroscopy (XPS) analysis has shown that after immersion into the ...
First electrochemistry of herbicide pethoxamid and its quantification using electroanalytical approach from mixed commercial product
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson ...
Interactive promotion of supercapacitance of rare earth/CoO3-based spray pyrolytic perovskite microspheres hosting the hydrothermal ruthenium oxide
(Elsevier, 2019)
Considerable promotion of RuO2 hosted by perovskite-like structure of rare eartheCoO3 composite and
vice versa supercapacitive performances is reported. Spherical, sub-mm-sized, regular spheres of
La0.6Sr0.4CoO3 (LSCO), ...
Catalysis of oxygen reduction on Au modified by Pd nanoislands in perchloric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited ...
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. ...
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 ...
