Hydrogen, a new energy carrier that can replace traditional fossil fuels, is seen as one of the most promising clean energy sources. The use of renewable electricity to drive hydrogen production has very broad prospects for addressing energy and environmental problems. Therefore, many researchers favor electrolytic water due to its green and low-cost advantages. The electrolytic water reaction comprises the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). Understanding the OER and HER mechanisms in acidic and alkaline processes contributes to further studying the design of surface regulation of electrolytic water catalysts. The OER and HER catalysts are mainly reviewed for defects, doping, alloying, surface reconstruction, crystal surface structure, and heterostructures. Besides, recent catalysts for overall water splitting are also reviewed. Finally, this review paves the way to the rational design and synthesis of new materials for highly efficient electrocatalysis.
氢气作为一种能够替代传统化石燃料的新能源载体，被视为最具前景的清洁能源之一。利用可再生电力驱动制氢在解决能源和环境问题方面具有非常广阔的前景。因此，许多研究人员青睐电解水，因其具有绿色和低成本的优势。电解水反应包括析氧反应（OER）和析氢反应（HER）。了解酸性和碱性过程中的OER和HER机制有助于进一步研究电解水催化剂的表面调控设计。主要综述了OER和HER催化剂在缺陷、掺杂、合金化、表面重构、晶体表面结构和异质结构方面的情况。此外，还综述了近期用于全水分裂的催化剂。最后，本综述为合理设计和合成用于高效电催化的新材料铺平了道路。
