Abstract
Proton exchange membrane water electrolyser (PEMWE) possesses great significance for the production of high purity of hydrogen. To expedite the anodic oxygen evolution reaction (OER) that involved multiple electron–proton-coupled process, efficient and stable electrocatalysts are highly desired. Currently, noble-metal Ir-based materials are the benchmark anode due to its corrosion-resistant property and favourable combination of activity/stability. However, the large-scale deployment of PEMWE is usually constrained due to the use of the scarcest element iridium. In this review, we disclose the current research progress towards the non-iridium-based electrocatalysts for OER in acidic media, and then summarize some typical oxides that possesses good catalytic performance. Besides, we also present the unresolved problems and challenges in an attempt to enhance the activity/stability of these catalysts.
质子交换膜水电解槽（PEMWE）对于生产高纯度氢气具有重要意义。阳极氧进化反应（OER）涉及多个电子-质子耦合过程，为加快该反应的进行，高效稳定的电催化剂备受青睐。目前，贵金属铱基材料因其耐腐蚀性能和活性/稳定性的良好组合而成为基准阳极。然而，由于使用最稀缺的铱元素，PEMWE 的大规模应用通常受到限制。在这篇综述中，我们介绍了目前针对酸性介质中 OER 的非铱基电催化剂的研究进展，然后总结了一些具有良好催化性能的典型氧化物。此外，我们还介绍了在试图提高这些催化剂的活性/稳定性方面尚未解决的问题和面临的挑战。
