Electrochemical water splitting involving hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is a greatly promising technology to generate sustainable and renewable energy resources, which relies on the exploration regarding the design of electrocatalysts with high efficiency, high stability, and low cost. Transition metal phosphides (TMPs), as nonprecious metallic electrocatalysts, have been extensively investigated and proved to be high-efficient electrocatalysts in both HER and OER. In this minireview, a general overview of recent progress in developing high-performance TMP electrocatalysts for electrochemical water splitting has been presented. Design strategies including composition engineering by element doping, hybridization, and tuning the molar ratio, structure engineering by porous structures, nanoarray structures, and amorphous structures, and surface/interface engineering by tuning surface wetting states, facet control, and novel substrate are summarized. Key scientific problems and prospective research directions are also briefly discussed.
涉及析氢反应（HER）和析氧反应（OER）的电化学水分解是一种极具前景的可持续和可再生能源生产技术，该技术依赖于对高效、高稳定性和低成本电催化剂设计的探索。过渡金属磷化物（TMPs）作为非贵金属电催化剂，已被广泛研究，并被证明在HER和OER中都是高效电催化剂。在这篇综述中，我们对用于电化学水分解的高性能TMP电催化剂的最新进展进行了概述。总结了设计策略，包括通过元素掺杂、杂化和调整摩尔比进行组成工程，通过多孔结构、纳米阵列结构和非晶结构进行结构工程，以及通过调整表面润湿性、晶面控制和新型基底进行表面/界面工程。还简要讨论了关键科学问题和未来研究方向。
