A method for producing a catalytic electrode consisting essentially of an electrical conductor and an adherent deposit of catalytic metal which consists essentially of providing a catalytic metal selected from the group consisting of platinum, palladium, nickel, rhodium and iridium, providing a supporting electrical conductor that forms a protective oxide on its surface, said electrical conductor being selected from the group consisting of silicon, titanium, tantalum, and niobium, sputter etching a predetermined surface of said conductor with ions of an inert gas for a time sufficient to remove oxide therefrom and to introduce disorder into the surface, thereby making it chemically reactive and thus adherent to said catalytic metal, and depositing said catalytic metal onto said etched surface of said conductor in a minimum thickness of about 10 Angstroms at least in at least a catalytic amount, said etching and deposition being carried out under a partial vacuum.
