Ag/ZnO magnetic photocatalyst based on Bentonite (Ag/Fe3O4/ZnO/Bentonite) was synthesized by green method and investigated by various techniques: XRD, FT-IR, -EDAXSEM and VSM. To synthesize this nanocomposite, first Zno nanoparticles were synthesized on bentonite substrate by green method in the presence of vulgare extract and then Fe3O4 and Ag nanoparticles were prepared on ZnO/Bentonite. The prepared nanocomposite showed high photocatalytic properties for the decomposition of methylene blue (MB) and Eriochrome Black T (EBT) in the presence of sunlight, and the decomposition kinetics of MB and EBT followed the Langmuir-Hinslowwood model. On the other hand, the decomposition of colors and weight loss of the nanocomposite was very low after five tests, indicating that the synthesized magnetic nanocomposite has a high stability and is easily recoverable.
