%X By using nanometer-sized Fe3O4 as support, TiO2/SiO2/Fe3O4 coated particles were prepared by a sol-gel method. Its structure and morphology were characterized by XRD, TEM, and element analysis methods. The photocatalytic reactivity of TiO2/SiO2/Fe3O4 was studied with methyl orange solution. The results indicate that the TiO2/SiO2/FesO4 two-double coated particles are composed of SiO2 mesosphere and anatase TiO2 crust. The new photocatalyst has not only excellent photocatalytic activity but also good magnetic property that can make the callback easy.
