Two-dimensional (2D) nanomaterials, especially the inorganic ultrathin nanosheets with single or few- atomic layers, have been extensively studied due to their special structures and rich physical properties coming from the quantum confinement of electrons. With atomic-scale thickness, 2D nanomaterials have an extremely high specific surface area enabling their surface phase to be as important as bulk counterparts, and therefore provide an alternative way of modifying the surface phase for engineering the intrinsic physical properties of inorganic 2D nanomaterials. In this review, we focus on recent research concerning surface chemical modification strategies to effectively engineer the intrinsic physical properties of inorganic 2D nanomaterials. We highlight the newly developed regulation strategies of surface incorporation, defect engineering, and structure modulation of inorganic 2D nanomaterials, which respectively influence the intrinsic conductivity, band structure, and magnetism while maintaining the primary 2D freestanding structures that are vital for 2D based ultrasensitive electronic response, enhanced catalytic and magnetocaloric capabilities. Key learning points (1) Advantages of surface chemical modification for engineering intrinsic physical properties in 2D materials. (2) Tuning the electronic conductivity of inorganic 2D materials by surface incorporation. (3) Regulation of the band structure of inorganic 2D materials by defect engineering. (4) Introducing intrinsic magnetism in 2D materials by surface modulation. (5) Applications of surface modified inorganic 2D nanomaterials. 目录： 1 Introduction 2 Engineering intrinsic physical properties by surface chemical modification 2.1 Tuning electronic conductivity by incorporation 2.2 Regulation of the band structure by defect engineering 2.3 Introducing magnetism by surface modulation 3 Applications of surface modified 2D nanomaterials 3.1 2D nanomaterials with tunable conductivity for nano-electrode and sensor materials 3.2 Surface defect modified 2D nanomaterials for high efficient catalysts 3.3 2D magnetic superlattice for enhanced magnetocaloric effects 4 Conclusion and perspectives  |
