Abstract

Hydrogen has emerged as an important candidate for clean energy, owing to its environmentally friendly advantages. Electrolytic hydrogen production stands out as the most promising technology for hydrogen production. Therefore, the design of highly efficient electrocatalysts is significant to drive the application of hydrogen technologies. Platinum (Pt)-based catalysts are famous for their outstanding performance in the hydrogen evolution reaction (HER). However, the expensive cost limits its wide application. Ruthenium (Ru)-based catalysts have received extensive attention due to their relatively lower cost and HER performance similar to that of Pt. Nevertheless, the performance of Ru-based catalysts is still unable to meet industrial demands. Therefore, improving HER performance through the modification of Ru-based catalysts remains significant. In this review, the reaction mechanism of HER is analyzed and the latest research progress in the modification of Ru-based electrocatalysts is summarized. From the reaction mechanism perspective, addressing the adsorption of intermediates on the Ru-based electrocatalyst surface, the adsorption–activation of interface water molecules, and the behavior of interface water molecules and proposing solutions to enhance performance of Ru-based electrocatalyst are the main findings, ultimately contributing to promoting their application in the field of electrocatalysis.

钌基电催化剂在氢气进化反应方面的最新进展

氢由于其环境友好的优点，已成为清洁能源的重要候选。电解制氢是最有前途的制氢技术。因此，高效电催化剂的设计对推动氢技术的应用具有重要意义。铂基催化剂以其在析氢反应(HER)中的优异性能而闻名。然而，昂贵的成本限制了其广泛应用。钌基催化剂因其成本相对较低、HER性能与Pt相当而受到广泛关注，但其性能仍不能满足工业需求。因此，通过改性钌基催化剂来提高HER性能仍然具有重要意义。本文对HER的反应机理进行了分析，并对钌基电催化剂改性的最新研究进展进行了综述。从反应机理角度，主要研究了中间产物在ru基电催化剂表面的吸附、界面水分子的吸附活化、界面水分子的行为，提出了提高ru基电催化剂性能的解决方案，最终促进了ru基电催化剂在电催化领域的应用。
