As an important half-reaction for electrochemical water splitting, electrocatalytic hydrogen evolution reaction suffers from sluggish kinetics, and it is still urgent to search high efficiency non-platinum-based electrocatalysts. Mo-based catalysts such as Mo C, MoO , MoP, MoS , and MoN have emerged as promising alternatives to Pt/C owing to their similar electronic structure with Pt and abundant reserve of Mo. On the other hand, due to the adjustable topology, porosity, and nanostructure of metal organic frameworks (MOFs), MOFs are extensively used as precursors to prepare nano-electrocatalysts. In this review, for the first time, the progress of Mo-MOFs-derived electrocatalysts for hydrogen evolution reaction is summarized. The preparation method, structures, and catalytic performance of the catalysts are illustrated based on the types of the derived electrocatalysts including Mo C, MoO , MoP, MoS , and MoN . Especially, the commonly used strategies to improve catalytic performance such as heteroatoms doping, constructing heterogeneous structure, and composited with noble metal are discussed. Moreover, the opportunities and challenges in this area are proposed to guide the designment and development of Mo-based MOF derived electrocatalysts.
作为电化学水分解的一个重要半反应，电催化析氢反应动力学迟缓，寻找高效的非铂基电催化剂仍然十分迫切。诸如碳化钼、氧化钼、磷化钼、硫化钼和氮化钼等钼基催化剂，因其与铂相似的电子结构以及钼的储量丰富，已成为铂碳催化剂有前景的替代物。另一方面，由于金属有机框架材料（MOFs）具有可调控的拓扑结构、孔隙率和纳米结构，它们被广泛用作制备纳米电催化剂的前驱体。在本综述中，首次总结了源自钼基金属有机框架材料的析氢反应电催化剂的研究进展。基于衍生电催化剂的类型，包括碳化钼、氧化钼、磷化钼、硫化钼和氮化钼，阐述了催化剂的制备方法、结构和催化性能。特别地，讨论了提高催化性能的常用策略，如杂原子掺杂、构建异质结构以及与贵金属复合。此外，还提出了该领域的机遇和挑战，以指导钼基金属有机框架衍生电催化剂的设计与开发。
