Electrocatalytic hydrogen evolution reactions (HERs) are a key process for hydrogen production for clean energy applications. HERs have unique advantages in terms of energy efficiency and product separation compared to other methods. Molybdenum disulfide (MoS) has attracted extensive attention as a potential HER catalyst because of its high electrocatalytic activity. However, the HER performance of MoS needs to be improved to make it competitive with conventional Pt-based catalysts. Herein, we summarize three typical strategies for promoting the HER performance, , defect engineering, heterostructure formation, and heteroatom doping. We also summarize the computational density functional theory (DFT) methods used to obtain insight that can guide the construction of MoS-based materials. Additionally, the challenges and prospects of MoS-based catalysts for the HER have also been discussed.
电催化析氢反应（HERs）是清洁能源应用中制氢的关键过程。与其他方法相比，HERs在能源效率和产物分离方面具有独特优势。二硫化钼（MoS）因其高电催化活性作为一种潜在的HER催化剂而受到广泛关注。然而，MoS的HER性能需要提高，以使其能与传统的铂基催化剂竞争。在此，我们总结了三种提高HER性能的典型策略，即缺陷工程、异质结构形成和杂原子掺杂。我们还总结了用于获得可指导基于MoS材料构建的见解的计算密度泛函理论（DFT）方法。此外，还讨论了基于MoS的HER催化剂面临的挑战和前景。
