The oxygen evolution reaction (OER) is a research focus in the clean energy field because it is the core reaction in electrochemical water splitting, rechargeable metal–air batteries, etc. OER is a complicated four-electron process; thus, it suffers from slow reaction rates. Therefore, the exploration of efficient OER electrocatalysts has become a significant topic in the research of advanced energy materials. Transition metal compounds exhibit great potential as highly active OER electrocatalysts, and rational regulations have been applied to boost their OER performance. Among these strategies, anion regulation is an emerging but effective method to improve the OER activity of transition metal compounds. In this review, recent advances in anion-regulated multi-anion transition metal compounds as OER catalysts are introduced, including the synthesis methods, the regulation of anions and their effects on OER activity. Anion regulation during OER tests, i.e. surface oxidation of the catalysts, is also discussed in this review. Then, studies are introduced according to the type of regulated anion. This review is expected to provide further insight into the composition and structure regulation of OER catalysts and inspire further research into transition metal-based energy materials.

阴离子调控的多阴离子过渡金属化合物用于氧气逸出电催化的研究进展

氧气析出反应(OER)是清洁能源领域的研究重点,因为它是电化学水分解,可充电金属空气电池的核心反应。OER是一个复杂的四电子过程。因此,它具有反应速度慢的缺点。因此,探索有效的OER电催化剂已成为高级能源材料研究中的重要课题。过渡金属化合物作为高活性OER电催化剂具有巨大的潜力,并且已经采用合理的规定来提高其OER性能。在这些策略中,阴离子调节是一种新兴但有效的方法,可提高过渡金属化合物的OER活性。在这篇综述中,介绍了作为OER催化剂的阴离子调节型多阴离子过渡金属化合物的最新进展,包括合成方法,阴离子的调节及其对OER活性的影响。OER测试中的阴离子调节,在本综述中还将讨论催化剂的表面氧化。然后,根据受调节阴离子的类型进行了研究。预期该评论将提供对OER催化剂的组成和结构调节的进一步了解,并激发对基于过渡金属的能源材料进行进一步研究的灵感。
