摘要：
Anatase TiO2 nanoparticles were synthesized by using HTiO3 as raw material and adopting TiOSO4 solution neutralizing process. The results show that the hydrolytic reaction temperature and time, molar ratio of urea to Ti precursors (R), volume ratio of distilled water to the TiOSO4 solution (F) determine the yield of TiO2; the average crystalline size of TiO2 nanoparticles can be controlled through the sintering temperature and the optimum temperature is about 600 degrees C; the TiO2 particles have good photocatalytic activity for decolorization of methyl orange.
