Green synthesis of Fe3O4-Ag nanoparticles without inert gas protection Used in photocatalytic degradation of metal orange

Facil synthesis of Fe3O4-Ag nanocomposites as magnetically recyclable nanocatalyst via reflux process at 80 °C for 3h followed by reduction of Ag+ using green tea leaves extract as the natural source of reducing and stabilizing agent without any surfactant. The structure, mor-phology, thermal behaviour and magnetic properties of the product were characterized by X-raypowder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), respectively. The photocatalytic activity of product for azo dyes such as methyl orange (MO),were studied. It was found that Fe3O4 -Ag is an efficient catalyst and can also be rapidly separated from the reaction medium using a magnet without a significant loss in its catalytic activity and used several times.
