Abstract

An attempt is made to reduce the use of IrO2 by the IrO2-SnO2-Sb2O5 intermediate layer which is necessary to avoid the growth of insulating titanium oxide on the titanium substrate for oxygen evolution ã-MnO2 type nanocrystalline Mn-Mo-Sn-O/Ir1-x-ySnxSbyO2+0.5y/Ti anodes in 0.5 M NaCl solution of pH 1 at 25°C. These electrodeposited Mn-Mo-Sn-based triple oxide anodes showed about 97.2-98.6 % oxygen evolution efficiency at high current density of 1000 A.m-2 in 0.5 M NaCl solution of pH 1 at 25°C. The high oxygen evolution efficiency of these triple oxide electrocatalysts maintained during prolonged electrolysis and even after the electrolysis for about two months.
