A metal electrode coated with electrocatalytic coating material is prepd. for use in electrolytic process. A valve metal, i.e. metal substrate, is titanium, tantalum, zirconium, tungsten, aluminium, niobium or their alloy, and coating material contains platium compd.. The produced metal electrode is used in electrolytic process of halogen compds. and acid compds. This is esp. suitable for chloride- alkali electrolytic process. This electrode improves a resistance to passivity.
