- 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.
