Firstly, nanoscale g-C3N4 sheets were synthesized via a hydrothermal method using urea as the raw material. Then, ZnO and Fe2O3 nanosize particles were prepared by solvent evaporation and ion exchange method, respectively. ZnO/g-C3N4 and Fe2O3/g-C3N4 photocatalysts were obtained by combining them with g-C3N4. Finally, the prepared composite photocatalysts were characterized by ultraviolet-visible diffuse reflectance spectroscopy, transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy, and their photocatalytic performance was investigated. Preliminary results showed that ZnO/g-C3N4 and Fe2O3/g-C3N4 photocatalysts exhibited excellent photocatalytic performance, which was better than pure g-C3N4 for the degradation of organic pollutants. Further research will be important for optimizing the preparation of composite photocatalysts and their application in environmental remediation.Keywords: g-C3N4; photocatalyst; ZnO; Fe2O3; composite material
