Electrocatalytic water splitting is considered as a promising route to use renewable energy for hydrogen production; however, its industrial application is limited by the anodic reaction, oxygen evolution reaction (OER). The key solution to unleash this constrain is to find an electrocatalyst that reduces the overpotential (η) of OER. Among the various electrocatalysts, perovskites have attracted intense attention recently for their high OER performance and low cost. To realize the commercial potential of perovskites, understanding its surface chemistry, including leaching, reconstruction, and lattice oxygen participated OER, is crucial to develop the next-generation perovskite catalysts,. In this Review, the perovskite surface stability is emphasized to be closely related to the chemical component of perovskite surface, which can be well controlled by surface engineering and further improves its OER performance. A new descriptor (stability level) is proposed to highlight the relationship between OER performance and surface stability of perovskite. This descriptor will provide potential strategies to optimize OER catalytic performance by tuning surface structure of perovskite.

钙钛矿表面稳定性对析氧反应电催化的调控

电催化水分解被认为是利用可再生能源制氢的一条有前途的途径；然而，其工业应用受到阳极反应、析氧反应（OER）的限制。释放这种限制的关键解决方案是找到一种能降低 OER 过电位 (η) 的电催化剂。在各种电催化剂中，钙钛矿最近因其高 OER 性能和低成本而备受关注。为了实现钙钛矿的商业潜力，了解其表面化学，包括浸出、重构和晶格氧参与的 OER，对于开发下一代钙钛矿催化剂至关重要。在这篇综述中，强调钙钛矿表面稳定性与钙钛矿表面的化学成分密切相关，可以通过表面工程很好地控制并进一步提高其OER性能。提出了一种新的描述符（稳定性水平）来强调 OER 性能与钙钛矿表面稳定性之间的关系。该描述符将提供通过调整钙钛矿表面结构来优化 OER 催化性能的潜在策略。
