光催化技术的发展日益成熟，其中石墨氮化碳(g?C3N4)作为一种能够响应可见光的非金属催化剂，因其具有可调节的能带结构，较高的物理化学稳定性以及环境友好等特点，在太阳能转换和环保领域得到了广泛的关注，成为新的研究热点。但是其自身也存在一些缺陷，例如比表面积小、光生电子空穴对易复合、光能利用率不高等，限制了g?C3N4在实际生产生活中的应用。因此结合国内外g?C3N4领域的发展和研究成果，从发展过程、合成方法、改性优化、性能应用等方面对g?C3N4进行了总结，并对如何进一步提高g?C3N4性能进行了展望。

The photocatalysis technology becomes more and more mature. As a non?metallic visible light responsive catalyst, carbon nitride (g?C3N4) has attracted wide attention in the field of solar energy conversion and environmental protection due to its adjustable band gap structure, high physicochemical stability and environmental friendliness. It has become a new research hotspot. However, g?C3N4 also has some defects, such as small specific surface area, recombination of photogenerated electron and holes, and low utilization rate of light energy,which limit the application of g?C3N4 in practice.Therefore,the review focus on the development and research results of g?C3N4,and summarizes g?C3N4 from the aspects of development process,synthesis method, performance application,modification and optimization,and predicts how to further improve the performance of g?C3N4 to cope with the future development of the world.
