Abstract

The invention relates to an electrode for evolution of gas in electrolytic processes comprising a substrate of valve metal and a catalytic coating comprising two layers. A first layer comprising oxides of valve metal, ruthenium and iridium and a second layer comprising one or more metals chosen from amongst elements of the platinum group.
