| 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 dis-cussed. 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%.
