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 ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Electrochemical behavior of esomeprazole: Its determination at Au electrode as standard and in injection powder combined with the study of its degradation
(Elsevier Science Sa, Lausanne, 2019)
Esomeprazole is the most effective of the proton-pump inhibitors for the acid-related diseases and at first was examined for the electroanalytical purposes. The drug standard and as a content of injection powder was ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Application of the general theory of disperse deposits formation in an investigation of mechanism of zinc electrodeposition from the alkaline electrolytes
(Elsevier, 2017)
In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA ...
Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier Science Sa, Lausanne, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
Mass transfer effect in electrochemical oxidation of methanol at platinum electrocatalysts
(Elsevier Science Sa, Lausanne, 2004)
The influence of the mass transfer on the electrochemical oxidation of methanol was investigated at a rotating disk electrode with smooth polycrystalline Pt and high area carbon supported Pt (Pt/C) as the electrocatalysts. ...
Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Journal of Electroanalytical Chemistry, 2021)
Hydrated iridiumoxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
Experimental study of zinc morphology in alkaline electrolyte at low direct and pulsating overpotentials
(Elsevier Sequoia SA, 2000)
A possible mechanism of the formation of spongy zinc electrodeposits is considered. The confirmation of the proposed semiquantitative mathematical model is performed in zinc electrodeposition onto copper wire from a 0.1 M ...
