β¦ Synopsis
The chlorine evolution reaction has been investigated on D.S.A. type electrodes in 5.13 M Nail solution. A large amount of potentiostatic current-potential and impedance-potential data has been collected over a wide potential and frequency range. The current-potential and impedance-potential data has been reduced by curve fitting to a series of parameter curves. The impedance-potential data were analysed by two methods: an equivalent circuit and the parameter curves C,,

Requisites for electrode materials to be suitable for technological applications are outlined and discussed. Oxides with metallic or quasi-metallic conductivity meet these requirements best. Most of these electrodes are prepared by thermal procedures. It is shown that the temperature of preparation
The chlorine evolution reaction on platinum and several alloys was studied by galvanostatic polarization measurements. Linear relationships are found between logarithmic current density, the electrode potential and the coverage of oxide, through the d-band vacancy in the electrode. Logarithmic excha
The chlorine evolution reaction was investigated on several oxide electrodes. The active site on the electrode surface is concluded to be the metal site, based on the dependence of the anodic current on pH of the electrolyte. The reaction mechanism can be determined by the d-electron configuration i
