Perovskite oxides are studied as electrocatalysts for oxygen evolution reactions (OER) because of their low cost, tunable structure, high stability, and good catalytic activity. However, there are two main challenges for most perovskite oxides to be efficient in OER, namely less active sites and low electrical conductivity, leading to limited catalytic performance. To overcome these intrinsic obstacles, various strategies are developed to enhance their catalytic activities in OER. In this review, the recent developments of these strategies is comprehensively summarized and systematically discussed, including composition engineering, crystal facet control, morphology modulation, defect engineering, and hybridization. Finally, perspectives on the design of perovskite oxide-based electrocatalysts for practical applications in OER are given.
钙钛矿氧化物因其成本低、结构可调、稳定性高和催化活性好而被研究用作析氧反应（OER）的电催化剂。然而，大多数钙钛矿氧化物在OER中高效发挥作用存在两个主要挑战，即活性位点较少和电导率较低，导致催化性能受限。为了克服这些内在障碍，人们开发了各种策略来提高它们在OER中的催化活性。在这篇综述中，全面总结并系统讨论了这些策略的最新进展，包括组成工程、晶面控制、形貌调制、缺陷工程和杂化。最后，给出了关于用于OER实际应用的钙钛矿氧化物基电催化剂设计的展望。
