ABSTRACT:
Disclosed is an oxygen evolution anode for evolving oxygen without chlorine evolution in electrolysis of aqueous solutions of sodium chloride having high performance and durability with decreased amount of the precious metal(s) in the intermediate layer to decrease manufacturing cost and to ease problem of the resources. The oxygen evolution anode comprises an electroconductive substrate, an intermediate layer and an electrocatalyst. The intermediate layer prepared by calcination consists of multiple oxide of the platinum group element(s), Sn and Sb, with the Sn/Sb ratio of 1-40 and with the sum of Sn and Sb of 90 cationic % or less. The electrocatalyst is prepared by anodic deposition and consists of 0.1-3 cationic % of Sn, 0.2-20 cationic % of Mo and/or W and the balance of Mn.
