Abstract:Two-dimensional (2D) materials possess nanoscale thickness with large aspect ratios on the other two dimensions.The ultrahigh surface-to-volume ratio of 2D materials is the most important property different from their bulk counterparts,and is beneficial for mass and heat transport,and ion diffusion.Among the various 2D materials,carbon-based materials have attracted tremendous attentions since the first explosive research on graphene.Therefore,they provide opportunities for applications in adsorption,catalysis,and electrical energy storage.The porous structure of such carbon materials is a key influence on the properties of these 2D materials.This review focuses on recent developments in synthesis strategies for 2D carbon-based materials,especially the preparation of carbon nanosheets and carbon-inorganic hybrids/composites nanosheets.The main factors influencing the porous structure of the material are discussed for each method.Applications of the materials are introduced,mainly in the fields of adsorption,heterogeneous catalysis,and electrical energy storage.Finally,the leading-edge issues of novel 2D carbon-based materials for the future are discussed.
