【 摘 要 】

Fe3O4/CuO/ZnO/nanographene platelets (Fe3O4/CuO/ZnO/NGP) with varied ZnO loadings have been synthesized using a sol-gel method followed by hydrothermal method. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) confirmed the formation of the Fe3O4/CuO/ZnO/NGP composites. All of the samples showed the presence of graphene nanoplatelets incorporating Fe3O4, CuO and ZnO structures and exhibited ferromagnetic behavior at room temperature. The composites showed photocatalytic activity under UV irradiation, which was used to affect the degradation of methylene blue. The Fe3O4/CuO/ZnO/NGP composites showed superior photocatalytic activity than the Fe3O4/CuO/ZnO materials.
