In this research, first a binary nanocomposite of magnetic recyclable photocatalyst Fe3O4/TiO2, was synthesized by sol gel technique. Then, in order to enhance the photocatalytic activity of the synthesized nanocomposite, it was deposited by silver nanoparticles for using in degradation of organic pollutants 2, 4-dichlorophenol (2, 4-DCP) under visible light. A range of analytical techniques including XRD, FESEM/EDX, DRS, VSM and N2 physisorption were employed to reveal the crystal structure, morphology and property of the nanocomposites. We obtained 32% and 55% degradation of 2, 4-DCP under visible light after 180 min irradiation in the presence of Fe3O4/TiO2 and Fe3O4/TiO2/Ag respectively. Thus, the excellent visible light photocatalytic activity of Fe3O4/TiO2/Ag sample can be attributed to the surface plasmon resonance effect of Ag nanoparticles deposited on Fe3O4/TiO2 nanocomposite.
