IrO{sub}2/Ti supported γ-MnO{sub}2 type Mn-Mo-Sn oxide electrodes were prepared by electrodeposition from MnSO{sub}4-Na{sub}2MoO{sub}4-SnCl{sub}4 solutions of pH -0.1～0.5 at 600 Am{sup}(-2) and 90°C for 60～90 min. The electrodes consist of Mn{sup}(3+), Mn{sup}(4+), Mo{sup}(6+) and Sn{sup}(4+) in the form of nanocrystalline single phase triple oxide. The performance of electrodes for oxygen evolution reaction during electrolysis of 0.5 M NaCl of pH 8.7 was examined at 1000 Am{sup}(-2). Anodic deposition in 0.2 M Mn{sup}(2+)-0.003 M Mo{sup}(6+)-0.006 M Sn{sup}(4+) electrolyte of pH -0.1 for 60 min guaranteed the stable electrode performance of 100 and 94% oxygen evolution efficiencies before and after electrolysis for more than seven months. Durability of the electrode was further improved by repeated deposition.
