Abstract

Designing economical oxygen evolution reaction (OER) electrocatalysts with high activity and long-term stability is essential to promote the scale-up applications of proton exchange membrane water electrolyzer (PEMWE) for hydrogen production. Ruthenium (Ru) -based materials with high intrinsic activity are hailed as the most promising catalysts, but still infeasible for practical application considering their long unresolved poor stability (only dozens of lifespan). Thus, tremendous efforts have been devoted to uncovering the degradation mechanisms and developing stabilization strategies for the Ru-based catalysts. In this review, starting from summarizing the fundamental understanding of deactivation mechanisms, a picture of the stability issue of Ru-based catalysts is proposed, which is followed by a detailed discussion on the recently developed strategies and progress made on enhancing durability. Finally, insights on the prospects for the future development of stable and practical Ru-based OER catalysts are provided.

质子交换膜水电解槽中用于 OER 的钌基催化剂的降解机制和稳定策略

设计具有高活性和长期稳定性的经济型氧进化反应（OER）电催化剂对于促进质子交换膜水电解槽（PEMWE）制氢的规模化应用至关重要。具有高固有活性的钌（Ru）基材料被誉为最有前途的催化剂，但由于其长期稳定性差（只有几十个寿命）的问题尚未得到解决，因此在实际应用中仍不可行。因此，人们一直致力于揭示 Ru 基催化剂的降解机制和开发稳定化策略。在这篇综述中，首先总结了对失活机制的基本认识，然后提出了 Ru 基催化剂稳定性问题的图景，接着详细讨论了最近开发的提高耐久性的策略和进展。最后，对未来开发稳定实用的 Ru 基 OER 催化剂的前景提出了见解。
