摘      要：MXenes,a new family of functional two-dimensional(2 D) materials,have shown great potential for an extensive variety of applications within the last *** defects and functional groups in MXenes are known to have a tremendous influence on the functional *** this review,we focus on recent progress in the characterization of atomic defects and functional group chemistry in MXenes,and how to control them to directly influence various properties(e.g.,electron transport,Li^(+) adsorption,hydrogen evolution reaction(HER) activity,and magnetism) of 2 D MXenes *** structural transformations such as oxidation and growth induced by atomic defects in MXenes are also *** review thus provides perspectives on property optimization through atomic defect engineering,and bottom-up synthesis methods based on defect-assisted homoepitaxial growth of MXenes.
