简要介绍了钙钛矿氧化物的结构特点与其在电催化领域的研究现状。钙钛矿氧化物作为电催化剂其催化活性的强弱与电子结构有着密切联系,总结了钙钛矿材料电催化性能的有效调控机制,包括A、B位掺杂和缺陷调控等策略。目前关于钙钛矿氧化物电催化反应的机理研究相对薄弱,严重制约了钙钛矿材料在电催化领域的应用。因此建立钙钛矿结构与电催化活性的内在联系,可以为未来开发高效经济电催化剂提供理论指导。

The structure characteristics of perovskite oxide and its research status in the field of electrocatalysis have been briefly introduced.The electrocatalytic activity of perovskite oxide is closely related to its electronic structure.The effective regulation methods of the electrocatalytic performance of perovskite are reviewed,including A,B doping and defect regulation strategies,etc.At present,the research on the regulation mechanism of perovskite electrocatalytic activity is relatively weak,which seriously restricts the application of perovskite in the field of electrocatalysis.Therefore,the internal relationship between the structure and electrocatalytic activity of perovskite was established to provide theoretical guidance for the development of efficient and economical electrocatalysts in the future.
