Abstract

In this study, Fe3O4/CuO/TiO2/NGP/Ag composites were synthesized by using a two-step - sol-gel and co-precipitation - method. The crystal structure, optical properties, and thermal properties of the prepared samples were characterized by X-ray Diffraction (XRD), ultraviolet-visible (UV-Vis) absorbance and thermogravimetric analysis (TGA), respectively. The Fe3O4/CuO/TiO2/NGP/Ag composites consist of cubic spinel (Fe3O4), anatase (TiO2), monoclinic (CuO), cubic (Ag), and graphitic like structure (NGP). The plasmon resonance at 425 nm from Fe3O4/CuO/TiO2/NGP/Ag attributed to the silver nanoparticles. The obtained Fe3O4/CuO/TiO2/NGP/Ag composites exhibited good photocatalytic activity toward degradation of methylene blue (MB) under visible and UV light irradiation as compared with Fe3O4/CuO/TiO2/NGP composites. Experiments confirmed that hole scavenging was the primary active species in photocatalytic activity. A four-time cycling reusability test substantiated that the composites were photostable.
