Hydrogen is a fuel with a potentially zero-carbon footprint viewed as a viable alternative to fossil fuels. It can be produced in a large scale via electrochemical water splitting using electricity derived from renewable sources, but this would require highly active, inexpensive, and stable hydrogen evolution reaction (HER) catalysts to replace the Pt benchmark. Transition-metal phosphides (TMPs) are potential Pt replacements owing to their generally high activity as well as versatility as HER catalysts for different pH media. This review summarizes the recent progress in the development of TMP HER electrocatalysts, focusing on the strategies that have been recently explored to tune the activity in acidic, neutral, and basic media. These strategies are the doping of TMPs with metal and nonmetal elements, fabrication of multimetallic phosphide phases, and construction of multicomponent heterostructures comprising TMPs and another component such as a different TMP or a metal oxide/hydroxide. The synthetic methods utilized to design the catalysts are also presented. Finally, the challenges still remaining and future research directions are discussed.

多金属和掺杂过渡金属磷在不同pH值下析氢反应的最新研究进展

氢是一种潜在的零碳足迹的燃料，被认为是化石燃料的可行替代品。它可以通过使用可再生资源产生的电能通过电化学水分解来大规模生产，但这将需要高活性，廉价且稳定的氢气析出反应（HER）催化剂来代替Pt基准。过渡金属磷化物（TMPs）由于其通常的高活性以及作为用于不同pH介质的HER催化剂的多功能性而成为潜在的Pt替代品。这篇综述总结了TMP HER电催化剂开发的最新进展，重点是最近探索的用于调节酸性，中性和碱性介质中活性的策略。这些策略是用金属和非金属元素掺杂TMP，制备多金属磷化物相，以及构建包含TMP和另一种组分（例如不同的TMP或金属氧化物/氢氧化物）的多组分异质结构。还介绍了用于设计催化剂的合成方法。最后，仍然存在的挑战和未来的研究方向进行了讨论。
