Two-dimensional(2D) layered graphitic carbon nitride nanosheets(CNNS) have an anisotropic two-dimensional geometry and aromatic p-π conjugated backbone, a highly open planar structure and high specific surface area, and enhanced charge-carriers transfer rate and adjustable band gap related to the layer thickness, and become one of the top two-dimensional layered materials for research. This article reviews various preparation and modification methods and applications of carbon nitride nanosheets in environmental protection, energy conversion, and biosensing, etc., in recent years. Finally, it can be concluded that exploring the new preparation methods of carbon nitride nanosheets with high quality and finding more applications of the photocatalysis are the focus of the future research.
