A novel of visible light induced photodegradation of methyl orange over Fe3O4-Ag3PO4@AgI photocatalyst has been observed. The nanoparticles have been synthesized by a facile and effective in-situ ion exchange method and characterized by scanning electron microscopy (SEM), X-ray diffraction meter (XRD) and UV−visible diffuse reflectance spectroscopy. The results show that the magnetic nanoparticles and AgI molecules are immobilized on surface of Ag3PO4 without the loss of photo functionality and magnetic properties. The Fe3O4-Ag3PO4@AgI has exhibited higher photocatalytic activity better than Ag3PO4@AgI and Ag3PO4 respectively. The photocatalytic activity of Fe3O4-Ag3PO4@AgI was evaluated by degradation of the methyl orange nearly 100% after short irradiation time with a good recyclability.
