用酒石酸辅助法制备了La1-xSrxCoO3系列钙钛矿氧化物，结果表明，采用该方法可在较低温度下形成高比表面的钙钛矿Sr取代La有助于形成均相多孔的表面，提高氧化物的比表面,电化学研究表明，钙钛矿氧化物膜电极Ni／La1-xSrxCoO3在碱性溶液中表现出很高的析氧电催化活性和良好的稳定性.
La1-xSrxCoO3 series perovskite oxides were prepared by the tartaric acid-assisted method. The results show that using this method can form perovskite with high specific surface area at lower temperature. The substitution of La for La can help to form a homogeneous porous surface and increase The specific surface area and electrochemical studies of oxide show that perovskite oxide film electrode Ni / La1-xSrxCoO3 has high oxygen evolution electrocatalytic activity and good stability in alkaline solution.
