The oxygen evolution reaction (OER) is a critical process in various sustainable energy technologies. Despite substantial progress in catalyst development, the practical application of OER catalysts remains hindered by the ongoing challenge of balancing high catalytic activity with long-term stability. We explore the inverse trends often observed between activity and stability, drawing on key insights from both experimental and theoretical studies. Special focus is placed on the performance of different electrodes and their interaction with acidic and alkaline media across a range of electrochemical conditions. This Perspective integrates recent advancements to present a thorough framework for understanding the mechanisms underlying the activity-stability relationship, offering strategies for the rational design of next-generation OER catalysts that successfully meet the dual demands of activity and durability.
析氧反应（OER）是各种可持续能源技术中的关键过程。尽管在催化剂开发方面取得了重大进展，但OER催化剂的实际应用仍然受到持续挑战的阻碍，即在高催化活性与长期稳定性之间取得平衡。我们借鉴实验和理论研究的关键见解，探讨了活性与稳定性之间经常观察到的相反趋势。特别关注不同电极在一系列电化学条件下的性能及其与酸性和碱性介质的相互作用。本综述整合了近期的进展，以提供一个全面的框架来理解活性-稳定性关系背后的机制，为合理设计成功满足活性和耐久性双重需求的下一代OER催化剂提供策略。
