| Abstract: | Oxygen evolution reactions on SrFeO3 were investigated in alkaline and acidic solutions. It was found that the catalytic activity for the oxygen evolution reaction in the alkaline solution is high. The following reaction steps (V)+Fe+2H2O→(O)+FeOH2+2H++2e? in acidic solution and FeOH+OH?→FeO?+H2O in alkaline solution are presumed to be rate-controlling in the anodic evolution of oxygen on SrFeO3 electrode, where (V) denotes oxygen vacancy on the electrode surface. The reaction mechanism and the catalytic property are discussed in connection to the band structure of the oxide. |
