Abstract

Abstract: The Ti/IrOx-TiO2/IrO2 electrode with iridium-titanium oxide interl ayer (n(Ir)/n(Ti)=49 (2), 9 (3), 4 (4), 1.5 (5)) was prepared by the i mpregation-thermal decomposition method. Compared with the conventional Ti/IrO 2 electrode (1), it not only increased its electrocatalytic activity for oxyge n evolution but also greatly improved its service life.

Key words: titanium nitride, chloro-iridic acid, titanium oxide, iridium oxide, interlayer, electrocatalysis
