The structure characteristics and the electrochemical behavior of Pt(Cu)/C electrocatalysts synthesized by consecutive deposition of copper and platinum on carbon-support microparticles is studied. The stability and catalytic activity of Pt(Cu)/C materials in reactions of oxygen electroreduction...
The effect of electrochemical and gas-phase activation of high-surface-area carbon black Ketjen Black EC 600 DJ on its stability and electrochemical capacitance is studied. The electrochemical activation is carried out according to the “start–stop” protocol (1–1.5 V, 0.5 V/s). The stability of...
Calixarenesulfonic acid complexation with perchloric acid is studied. The stoichiometric composition of the complex is shown to be calixarene/HClO4 = 1/1. The complex is most stable against humidity changes as far as its proton-conducting properties are concerned. Its specific proton...
Olivine-structured LiFe0.97Ni0.03PO4/C/Ag nanomaterials of varying dispersibility are prepared by using sol–gel synthesis with subsequent milling. The materials are certified using X-ray diffraction analysis, scanning electron microscopy, low-temperature nitrogen adsorption, and electrochemical...
The corrosion current density of Ni–Re alloy (15.8 wt % Re) was estimated using recently developed method of compensating additives. The alloy was fabricated by the electrodeposition in the form of bulk specimen and the powder prepared of this specimen. The electrodeposition was performed in...
A method for the analysis of corrosion process involving two cathodic reactions and one anodic reaction is proposed. By way of example, this method is used to calculate a particular cathodic polarization curve with two Tafel portions. The calculated polarization curve coincides with the...
The effect of volume variation at the possible dissociation equilibria of (MX4)2– anionic complexes in halide melts of bivalent metals are analyzed in terms of the mean-sphere approximation (MSA) of the statistical theory. Within the framework of the simplified model of charged hard spheres of...
