摘　　要：金属有机框架(MOFs)材料是一种由有机配体和具有金属离子的前驱体进行化学反应制得的有机-无机杂化材料。MOFs具有独特的晶体结构、可调的孔尺寸、形状和孔隙大小,在电催化领域备受关注。MOFs材料作为电催化剂存在稳定性差和催化活性低等不足。文章从微观形貌调控、配体调控、多金属调控和构建缺陷或者空位4个方面综述了提高金属有机框架电催化材料性能的策略,总结构建MOFs复合材料电催化剂和MOFs衍生材料电催化剂的相关研究,并对MOFs材料在电催化领域的应用前景进行展望。Metal-organic framework(MOFs)material is a kind of organic-inorganic hybrid material which is prepared by chemical reaction of organic ligand and precursor with metal ions.MOFs are highly valued in the field of electrocatalysis due to their unique crystalline structures,tunable pore sizes,shapes,and pore diameters.However,MOF materials used as electrocatalysts often suffer from poor stability and low catalytic activity.The article reviews strategies for enhancing the performance of MOF-based electrocatalytic materials from four aspects of microstructure regulation,ligand regulation,multimetal regulation,and the construction of defects or vacancies.It summarizes relevant research on MOF composite electrocatalysts and MOF-derived electrocatalysts,and also provides an outlook on the future application prospects of MOFs in the field of electrocatalysis.
