Abstract: An electrode suitable as chlorine-evolving anode in electrolytic cells and a method for obtaining thereof is provided. The electrode has a metal substrate coated with a catalytic composition made of thin layers based on oxides of tin, iridium and ruthenium and combines excellent characteristics of anodic potential and selectivity with respect to the reaction of chlorine evolution without resorting to the use of dopants such as platinum and palladium.
