PEROVSKITE OXIDE CATALYST FOR OXYGEN EVOLUTION REACTIONS |
摘要 |
A catalyst for an oxygen evolution reaction has a higher and longer-life catalytic activity than that of the conventional and expensive noble metal oxide catalysts, such as RuO2 and IrO2. An A-site ordered perovskite oxide catalyst (such as CaCu3Fe4O12 and CaMn3Mn4O12 etc.) as an oxygen evolution reaction catalyst is excellent in cost effectiveness. The catalyst has a high catalytic activity compared with a noble metal oxide catalyst, and a long repetition use life since it is extremely stable also under the oxidative reaction conditions. Use of the catalyst is expected to the important energy conversion reactions such as a charge reaction of a metal-air battery, an anode oxygen evolution reaction in the case of a direct water decomposition reaction by sunlight, etc. |
