摘　　要：金属有机骨架(MOFs)丰富的活性位点和多孔结构使其在电催化领域受到广泛关注。通过缺陷工程调控MOFs的分子结构和孔道结构,可改变其本征催化活性及质荷传输能力,有助于提升其电催化性能。本文介绍了缺陷MOFs的构筑方法及其在电催化水分解、氮还原和二氧化碳还原方面的应用,并对缺陷MOFs在电催化小分子转化领域的发展前景予以展望,以期为高效MOFs电催化剂的开发提供指导。Metal-organic frameworks(MOFs)have attracted extensive attention in the field of electrocatalysis due to their abundant active sites and high porosity.By modulating the molecular and pore structures of MOFs with defect engineering,their intrinsic reactivity,mass and charge transport capacity can be altered,which may promote the electrocatalytic performance of MOF catalysts.This article introduces the construction method of defective MOFs and their applications in electrocatalytic water splitting,nitrogen reduction,and carbon dioxide reduction.Moreover,the perspectives on the opportunities and challenges of defective MOFs for electrocatalytic application are conferred to instruct the controllable construction of MOF electrocatalysts.
