摘要: 本文在N2气氛下热缩聚法合成了高N含量的g-C3N4，随后通过水热合成法构筑了GO/g-C3N4界面复合材料，最后根据Fenton反应与光催化剂的协同效应，设计合成了Fe3O4/GO/g-C3N4复合光催化剂，并将它们应用于RhB的降解，进一步探讨了光促Fenton反应的降解机理。实验还发现，提高N含量与GO/g-C3N4界面效应均能有效提高光催化效率，此外，负载Fe3O4的复合光催化剂可通过外部磁场进行分离回收再利用，这也为实际应用提供了便利。
Abstract: In this paper, g-C3N4 with high N content was synthesized by thermal polycondensation under N2 atmosphere, and then a GO/g-C3N4 interface composite was constructed by a hydrothermal syn-thesis method. Finally, according to the synergistic effect of Fenton reaction and photocatalytic reaction, Fe3O4/GO/g-C3N4 composite photocatalysts were designed and synthesized, and applied them to the degradation of RhB, further explored the photocatalytic degradation mechanism of Fenton reaction. The experiment also found that increasing the N content and the GO/g-C3N4 in-terface effect can effectively improve the photo-catalytic efficiency. In addition, the composite photocatalyst loaded with Fe3O4 can be separated and recycled by external magnetic fields, which facilitates the practical applications of the catalyst.
