摘要:
石墨相氮化碳（g-C3N4）是具有二维层状结构的无金属半导体材料，以低成本富氮材料为前驱体就可制得。g-C3N4具有合适的禁带宽度、良好的热稳定性和化学稳定性以及绿色环保无污染等优点，被广泛应用于产氢、降解有机染料及CO2的还原等领域，因此在光催化领域有着诱人的应用前景。但纯g-C3N4比表面积小、光生载流子易复合，使其光催化性能受到一定的影响，所以需要不同的制备及改性方法来提高其光催化性能。归纳了g-C3N4的制备及改性方法，综述了近年来g-C3N4在印染、抗生素、重金属和农药等生产废水处理中的应用，并对g-C3N4今后在合成、改性方面的研究进行了展望。
Abstract:
Graphite phase carbon nitride (g-C3N4) is a metal-free semiconductor material with two-dimensional layered structure, which can be prepared by using low-cost nitrogen-rich materials as precursors.It has the advantages of suitable band gap width, good thermal, chemical stability, environment-friendly and pollution-free. It is widely used in hydrogen production, degradation of organic dyes and CO2 reduction and other fields, leading to an attractive application prospect in the field of photocatalysis. However, the photocatalytic performance of pure g-C3N4 is limited by its small specific surface area and the easy recombination of photogenerated carriers on it surface. Therefore, different preparation and modification methods are needed to improve its photocatalytic performance. The preparation and modification methods of g-C3N4 were summarized.The application of g-C3N4 on various industrial wastewater from printing and dyeing, antibiotics, heavy metals and pesticides in recent years was reviewed. The future research on the synthesis and modification of g-C3N4 was prospected.
