Using Fe3O4 nanoparticles as the kernel,SiO2 inert layer as the isolation layer,tetra-n-butyl titanate as the precursor,ammonium tungstate and ammonium nitrate as doping sources,magnetic W,Ncodoped TiO2 photocatalyst was prepared by low-temperature sol method. The properties of the magnetic photocatalyst were investigated by XRD,SEM,DRS and IR. The results indicate that the magnetic W,N-codoped TiO2 photocatalyst is spherical anatase nanoparticle with forbidden band width decreased by 0.66 eV. Under irradiation of xenon lamp for the simulated degradation of methyl orange by sunlight,the degradation rate of methyl orange can exceed 90% with 1 h of irradiation in presence of the magnetic W,N-codoped TiO2 photocatalyst.
