摘要：
In order to study the photo-Fenton properties of FeOCl combined with carbon materials, g-C3N4/FeOCl nanocomposites were prepared by a simple calcination method according to the different composite mass ratios of g-C3N4 and FeCl3·6H2O. Composition, structure, and optical properties of the composite samples tested by XRD, SEM, TEM, XPS, UV-vis DRS, EIS, and transient photocurrent testing. The results show that the g-C3N4/FeOCl composite has a layered nanorod stacking structure with the good light response and carrier separation capability. When the composite ratio of g-C3N4 to FeCl3·6H2O is 1∶20, it exhibits excellent photo-Fenton performance, and the degradation rate of rhodamine B (RhB) reaches 92.4%. And after three cycles, the efficiency of the composite material in degrading RhB remains at 80.1% that showing good stability. Based on the experimental results, the Z-type heterojunction between g-C3N4 and FeOCl was proposed to improve the separation efficiency of photo-generated carriers, and the possible mechanism of photo-Fenton degradation of RhB by Z-type heterojunction was discussed. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
