Renewable silver-amalgam film electrode for voltammetric monitoring of solar photodegradation of imidacloprid in the presence of Fe/TiO2 and TiO2 catalysts
(Elsevier, 2013)
A rapid and sensitive voltammetric method has been developed for the characterization and determination of the imidacloprid insecticide by means of square-wave voltammetry (SWV) with a silver-amalgam film electrode (Hg(Ag)FE) ...
The effect of rhodium nanoislands on the electrocatalytic activity of gold for oxygen reduction in perchloric acid solution
(Elsevier, 2013)
The effect of spontaneously deposited rhodium nanoislands on the electrocatalytic activity of polycrystalline gold, Au(poly), for oxygen reduction reaction (ORR) was studied using rotating disc electrode technique in 0.1 ...
Catalytic activities of Pt thin films electrodeposited onto Bi coated glassy carbon substrate toward formic acid electrooxidation
(Elsevier, 2014)
Formic acid oxidation was studied on platinum-coated bismuth deposits on glassy carbon substrate. The catalyst was prepared by a two-step process using chronocoulometry, i.e. controlled amount of Bi was electrodeposited ...
Electrocatalysis of hydrogen evolution on polycrystalline palladium by rhodium nanoislands in alkaline solution
(Elsevier, 2015)
Hydrogen evolution reaction (HER) was investigated on bimetallic Rh/Pd(poly) electrodes in alkaline solution. Bimetallic electrodes were obtained by a spontaneous deposition of rhodium on polycrystalline Pd. Characterization ...
Catalysis of oxygen reduction on electrochemically activated polycrystalline gold by Pd nanoislands in alkaline solution
(Elsevier, 2017)
Catalytic properties of electrochemically activated polycrystalline gold, Au(poly), modified by spontaneously deposited palladium nanoislands with the coverage below a monolayer were examined for the oxygen reduction ...
Methanol oxidation on Ru/Pd(poly) in alkaline solution
(Elsevier, 2018)
Polycrystalline Pd electrode, Pd(poly), is modified by Ru nanoislands using spontaneous deposition method. Coverage of Pd(poly) electrode with the deposited Ru are approx. 20, 30 and 50% as estimated from phase atomic force ...
Briggs-Rauscher reaction as a novel electrochemical detector for phosphate tungsten and phosphate molybdenum bronzes
(Elsevier, 2019)
Briggs-Rauscher (BR) oscillatory reaction is a chemical system very sensitive to different analyte addition. Changes in oscillatory dynamics, by analyte addition, could be successfully used for the determination of analyte ...
Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier, 2019)
Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution ...
Ru layers electrodeposited onto highly stable Ti2AlC substrates as cathodes for hydrogen evolution in sulfuric acid solutions
(Elsevier, 2016)
In this work, the hydrogen evolution reaction (HER) was studied on Ru coated Ti2AlC electrodes in 1.0 mol dm(-3) H2SO4 at 25 degrees C. Ti2AlC was found to be a highly stable substrate in sulfuric acid solutions due to the ...
Electrochemical determination of sildenafil citrate as standard, in tablets and spiked with human serum at gold and cystein modified gold electrode
(Elsevier, 2016)
Nonmedical use of sildenafil citrate (SC) requires new methods for drug determination in human serum and in tablets. SC as standard and in Sildena (R) tablets is determined by square wave voltammetry (SWV) in 0.1 M H2SO4 ...
