| Abstract: | The nanosize composite magnetic photocatalyst WO3/TiO2/SiO2/Fe3O4 have successfully been prepared by sol-gel method with magnetite Fe3O4 as a matrix,which has been prepared by hydrolysis-reduction of NH4Fe(SO4)2 and characterized by TEM.The factors to photocatalytic performance such as calcined temperature,doped content of tungsten oxide et al,are investigated.The photocatalytic degradation ratio of methylene blue comes up to 93% by the catalyst under UV-light with 365 nm after 1 h. |
