Molybdenum disulfide (MoS) has been recognized as one of the most promising catalysts to replace Pt for hydrogen evolution reaction (HER) electrocatalysis because of the elemental abundance, excellent catalytic potential, and stability. However, its HER efficiency is still below that of Pt. Recent research advances have revealed that the modification of pristine MoS is a very effective approach to boost its HER performance, including improving the intrinsic activity of sites, increasing the number of edges, and enhancing the electrical conductivity. In this review, we focus on the recent progress on the modification strategies of MoS for enhanced electrocatalytic hydrogen evolution. Moreover, some urgent challenges in this field are also discussed to realize the large-scale application of the modified-MoS catalysts in industry.

二硫化钼 (MoS) 已被认为是最有前途的催化剂之一，可以替代 Pt 用于析氢反应 (HER) 电催化，因为其元素丰度高、催化潜力优异且稳定。然而，其 HER 效率仍低于 Pt。最近的研究进展表明，对原始 MoS 的修饰是提高其 HER 性能的一种非常有效的方法，包括提高活性位的本征活性、增加边缘数量和增强导电性。在这篇综述中，我们重点介绍了用于增强电催化析氢的 MoS 修饰策略的最新进展。此外，还讨论了该领域的一些迫切挑战，以实现改性-MoS 催化剂在工业中的大规模应用。
