摘　　要：碳化钼(Mo_(2)C)因其与铂(Pt)相似的d带电子结构、宽pH适用性、易于合成、低成本等优势,成为一种很有前途的电催化剂。然而,纯Mo_(2)C存在导电性差、界面反应动力学慢、Mo-H结合能太强等缺陷。近年来,许多研究报道了改性Mo_(2)C基催化剂来提升其电催化析氢性能,基于此,综述了Mo_(2)C常用的制备工艺以及提高Mo_(2)C析氢性能的各种不同改性策略,深入分析了不同改性方式对Mo_(2)C析氢性能提高的内在原因。最后,提出了Mo_(2)C基电催化剂目前面临的挑战和未来的发展方向。Molybdenum carbide(Mo_(2)C)has become a promising electrocatalyst because of its similar d-band electronic structure to platinum(Pt),wide pH applicability,easy synthesis,and low cost.However,pure Mo_(2)C suffers from poor electrical conductivity,slow interfacial reaction kinetics,and too strong Mo-H bond.In recent years,many studies have reported the modification of Mo_(2)C-based catalysts to enhance their electrocatalytic hydrogen evolution performance.Based on this,this paper reviews the common preparation process of Mo_(2)C and various modification strategies to improve the electrocatalytic hydrogen evolution performance of Mo_(2)C.And intrinsic reasons for the improvement of Mo_(2)C hydrogen evolution performance by different modification methods are analyzed in deeply.Finally,the current challenges and future development directions of Mo_(2)C-based electrocatalysts are proposed.
