Abstract：The silica nanoparticles was prepared by hydrothermal as a hard template, different mass ratio of doped tin and titanium oxide were wrapped in the surface of SiO2 by sol-gel method.Thenthe SnO2/TiO2 mesoporous materials were synthesized by removing the silica template.The SnO2/TiO2 were characterized by SEM, the material was a porous structure and the average particle size was about 4 um.Photocatalytic experiment shows that in the mesoporous materials, the mesoporous material have better catalytic degradation effect on direct sky blue 5B, the mass ratio for SnO2/TiO2 of 95∶5 had the best effect on the dye, in 60 minute, the decolorization rate of direct sky blue 5B is 98 percent.With different Sn(IV) content, adsorbance capacity of the SnO2/TiO2 is different under the condition of lucifuge.
