Graphitic carbon nitride (g-C3N4) is a typical sp2 π conjugated polymer semiconductor material with a variety of unique physical and chemical properties. However, g-C3N4 obtained by a conventional calcination method has some shortcomings such as small specific surface area, a few exposed active sites, and a poor dispersibility in aqueous solution, restricting its practical application. Compared with bulk g-C3N4, g-C3N4 nanosheets obtained by different exfoliation processes have attracted much attention in the fields of energy, catalysis and sensing due to their high specific surface area, short carrier path, abundant active sites and large band gap. g-C3N4 has some disadvantages of nanosheet agglomeration, high energy consumption, long time consumption and low yield in the exfoliation preparation process. It is thus necessary to develop a green and cost-effective method for the preparation of g-C3N4 nanosheets. This paper reviewed the exfoliation mechanisms of top-down liquid exfoliation, chemical exfoliation and thermal exfoliation. The structure, composition, lamellar thickness and specific surface area of g-C3N4 nanosheets obtained by three methods were compared. In addition, some applications in photocatalysis were introduced, and the future development of g-C3N4 nanosheets was also prospected.

石墨相氮化碳（g-C3N4）是一种典型的sp2 π共轭体系聚合物半导体材料，具有多种独特的物理化学性质。但是，通过传统煅烧方式得到的g-C3N4存在比表面积小、暴露的活性位点少、在水溶液中分散性差等问题，限制了其实际应用。与块状g-C3N4相比，通过不同剥离工艺得到的g-C3N4纳米片具有比表面积高、载流子路径短、活性位点丰富、带隙大等优点，在能源、催化、传感等领域受到了广泛的关注。g-C3N4在剥离制备过程中存在纳米片团聚、能耗高、耗时长以及产量低等缺点。因此，有必要开发绿色且具有成本效益的g-C3N4纳米片制备方法。本文详细综述了自上而下的液相剥离、化学剥离和热剥离法的剥离机理，并对比了3种方法获得g-C3N4纳米片的结构、组成、片层厚度以及比表面积，同时介绍了其在光催化方面的应用进展，并对g-C3N4纳米片的进一步发展作出了展望。

摘要
收起

石墨相氮化碳（g-C3N4）是一种典型的sp2 π共轭体系聚合物半导体材料，具有多种独特的物理化学性质。但是，通过传统煅烧方式得到的g-C3N4存在比表面积小、暴露的活性位点少、在水溶液中分散性差等问题，限制了其实际应用。与块状g-C3N4相比，通过不同剥离工艺得到的g-C3N4纳米片具有比表面积高、载流子路径短、活性位点丰富、带隙大等优点，在能源、催化、传感等领域受到了广泛的关注。g-C3N4在剥离制备过程中存在纳米片团聚、能耗高、耗时长以及产量低等缺点。因此，有必要开发绿色且具有成本效益的g-C3N4纳米片制备方法。本文详细综述了自上而下的液相剥离、化学剥离和热剥离法的剥离机理，并对比了3种方法获得g-C3N4纳米片的结构、组成、片层厚度以及比表面积，同时介绍了其在光催化方面的应用进展，并对g-C3N4纳米片的进一步发展作出了展望。

Graphitic carbon nitride (g-C3N4) is a typical sp2 π conjugated polymer semiconductor material with a variety of unique physical and chemical properties. However, g-C3N4 obtained by a conventional calcination method has some shortcomings such as small specific surface area, a few exposed active sites, and a poor dispersibility in aqueous solution, restricting its practical application. Compared with bulk g-C3N4, g-C3N4 nanosheets obtained by different exfoliation processes have attracted much attention in the fields of energy, catalysis and sensing due to their high specific surface area, short carrier path, abundant active sites and large band gap. g-C3N4 has some disadvantages of nanosheet agglomeration, high energy consumption, long time consumption and low yield in the exfoliation preparation process. It is thus necessary to develop a green and cost-effective method for the preparation of g-C3N4 nanosheets. This paper reviewed the exfoliation mechanisms of top-down liquid exfoliation, chemical exfoliation and thermal exfoliation. The structure, composition, lamellar thickness and specific surface area of g-C3N4 nanosheets obtained by three methods were compared. In addition, some applications in photocatalysis were introduced, and the future development of g-C3N4 nanosheets was also prospected.
