ELECTROLYSIS ELECTRODE AND PRODUCTION METHOD THEREOF

摘要

An improved electrode for electrolysis, comprising: a titanium substrate; a porous platinum layer deposited on the outer surface of the titanium substrate, the porous platinum layer having an apparent density of 8 to 19 g/cm3; and at least one oxide of a metal selected from ruthenium, palladium and iridium three-dimensionally deposited within the pores and on the outer surface of the porous platinum layer. The electrode is prepared by a process comprising: forming the porous platinum layer on the titanium substrate, permeating a a solution of a compound of the metal dissolved in a solvent therefore into the pores of the porous platinum layer, and evaporating the solvent and thermally decomposing the compound in an oxidizing atmosphere to convert the compound to the at least one oxide of the metal in situ in the pores of the porous platinum layer.
