A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
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 ...
The electrochemical reduction of trinitrotoluene on a platinum wire modified by chemisorbed acetonitrile
(Elsevier, 2010)
The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. ...
Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni-MoO2 composite coating in alkaline solution
(Elsevier Science Sa, Lausanne, 2012)
As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier Science Sa, Lausanne, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
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 ...
Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
The potentiostatic current transients and the role of local diffusion fields in formation of the 2D lead dendrites from the concentrated electrolyte
(Elsevier, 2015)
Electrodeposition of lead from the concentrated nitrate electrolyte in the potentiostatic regime of electrolysis has been investigated by the analysis of the potentiostatic current transients and scanning electron microscope ...
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 ...
Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier B.V., 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 ...
