摘要
针对石墨相氮化碳(g-C_(3)N_(4))比表面积小、光生载流子复合快和可见光利用效率低等缺点,阐述了g-C_(3)N_(4)的改性方法,包括形貌调整、离子掺杂、半导体复合,旨在增大比表面积,加快电子-空穴对的分离,拓宽可见光响应范围;同时讨论了相应的改性方法对光催化性能的影响,从而达到提高光催化性能的目的;对g-C_(3)N_(4)的未来发展趋势进行了展望。
Aiming at the shortcomings of small specific surface area of g-C_(3)N_(4),fast recombination of photogenerated carriers and low utilization efficiency of visible light,the modification methods of g-C_(3)N_(4)are described,including morphology adjustment,ion doping,and semiconductor recombination,aiming to increase the specific surface area.To speed up the separation of electron-hole pairs and broaden the visible light response range;at the same time,the influence of the corresponding modification methods on the photocatalytic performance is discussed,so as to achieve the purpose of improving the photocatalytic performance;finally,the future development trend of g-C_(3)N_(4)is carried out outlook.
