摘　　要：Using ZnSO4 and TiCl4 as raw materials, nanometric TiO2 ZnO (ZnTiO3) is prepared at 180℃,0.8MPa by hydrothermal method. The effects of the reaction temperature and time on the nanometric TiO2 ZnO are also discussed. XRD shows that the product is TiO2 ZnO (ZnTiO3) with noncrystal phase, and it changes to rhombic form above 870℃. TEM measurement indicates that the TiO2 ZnO is spherical particles, and the average diameter of the particles is 20nm. The UV light absorption properties are detected by UV spectrophotometer. The results show that the nanometric TiO2 ZnO has strong absorption at 200～370nm and at visible region. Photodegradation of dyes in an aqueous solution is investigated using nanometric TiO2 ZnO as a photocatalyst. The results show that after 60min illumination, the decolorization rate of the acidic red B and acidic black 234 dye can be arrived at 100%.
