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.
