摘要：

By sol-gel way, Ce3+doped TiO2 sol can be synthesized, which use those chemicals: tetrabutyltitanate (the principal raw material), anhydrous ethanol (the solvent), glacial acetic acid (the inhibitor), and concentrated nitric acid (the catalyst). Different amount of Ce3+ doped TiO2 powders were obtained according to calcineding gel 3 h with different temperature. Different amount of Ce3+ doped TiO2 powders were characterized by means of X-ray diffraction (XRD). Used methylene blue as the simulation of organic dyes, the photoactivity impact of samples with different amount of Ce3+ doped was studied under ultraviolet light. Result shows: the photoactivity of Ce3+doped TiO2 was superior to the pure one. When 1.0% Ce3+ doped, heat treatment temperature was 650℃, the photoactivity of Ce3+-TiO2 was highest in all samples. The methylene blue degradation efficiency was 90.3% when the capacity of Fe3O4 in Fe3O4/Ce3+-TiO2 was 10%, the magnetic separation recovery rate was 96.8% when reaction time reach 8 h.
