Abstract

Silver (Ag) nanoparticles were successfully synthesized by a microwave-assisted method, then the prepared Ag nanoparticles were combined with Fe3O4 and ZnO to create Ag/Fe3O4/ZnO composites. The structure and properties of the composites at various Ag loadings were characterized using X-ray diffraction (XRD), Fourier Transform Infra-red (FT-IR) spectroscopy and ultraviolet-uisible (UV-Vis) absorbance measurements. UV-Vis absorbance confirms the presence of surface plasmon peak for Ag at ~440 nm. The prepared composites exhibit excellent activity in photocatalytic degradation within the UV light region, and 25 wt.% of Ag nanoparticles were found to be the most suitable loading. The hole was the major radicals to be involved in photocatalytic process. Finally, Ag/Fe3O4/ZnO composites could be easily recovered from the system using an external magnet and exhibited no significant loss of photocatalytic activity in the reuse process.
