Abstract
The behaviour of a mixed oxide coating thermally deposited on titanium has been examined with respect to the anodic discharge of chloride ions.
The electrochemical properties are similar to those of thermal Pt and Pt-Ir alloy electrodes: chlorine evolution takes place through an electrochemical-chemical mechanism, the 2Clads→Cl2 step being rate determining.
Evidence is given about the mechanical and chemical stability of the coating and about the satisfactory reproducibility of the catalytic properties. Moreover, the current efficiency for chlorine evolution appears to be at least 99% at high current densities (up to 16,000 A/m2).
