Exploration of electrocatalysts for clean and sustainable hydrogen generation from water splitting has received huge attention due to the depletion of fossil fuels and environmental pollution. Although platinum (Pt) is the most efficient catalyst for the hydrogen evolution reaction (HER), it has limitations for widespread applications due to its towering cost, scarcity and instability. Various catalysts such as precious/non-precious metal and metal-free catalysts have been developed for a viable HER process. Among them, ruthenium (Ru) based catalysts, which possess appropriate hydrogen bonding energy and reasonable price, have demonstrated strong potential as an alternative to Pt for the HER. In this review article, we summarize recently developed Ru-based electrocatalysts with superior HER performance, i.e., Ru on carbon supports, Ru phosphide based catalysts, and Ru coupled with transition metals. Finally, we discuss the challenges and perspectives of Ru-based catalysts in the HER research field.

析氢反应用钌基电催化剂的最新进展

由于化石燃料的消耗和环境污染，探索用于水分解产生清洁和可持续氢的电催化剂受到了极大的关注。尽管铂（Pt）是最有效的制氢反应（HER）催化剂，但由于其高昂的成本，稀缺性和不稳定性，因此在广泛的应用中存在局限性。对于可行的HER方法，已经开发了各种催化剂，例如贵/非贵金属和不含金属的催化剂。其中，具有合适的氢键能和合理的价格的钌（Ru）基催化剂显示出强大的潜力，可作为HER的Pt替代品。在这篇综述文章中，我们总结了最近开发的具有优异HER性能的Ru基电催化剂，即，碳载体上的Ru，磷化钌基催化剂以及Ru与过渡金属偶联。最后，我们讨论了钌基催化剂在HER研究领域中的挑战和前景。
