摘要
光催化技术的发展日益成熟,其中石墨氮化碳(g-C_(3)N_(4))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-C_(3)N_(4)在实际生产生活中的应用。因此结合国内外g-C_(3)N_(4)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-C_(3)N_(4)进行了总结,并对如何进一步提高g-C_(3)N_(4)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-C_(3)N_(4))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-C_(3)N_(4)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-C_(3)N_(4)in practice.Therefore,the review focus on the development and research results of g-C_(3)N_(4),and summarizes g-C_(3)N_(4)from the aspects of development process,synthesis method,performance application,modification and optimization,and predicts how to further improve the performance of g-C_(3)N_(4)to cope with the future development of the world.
