Abstract

Nanocrystalline TiO_2 was prepared by sol-gel method. A ccording to the DTA curve, it is found that anatase phases of nanocrystalline Ti O_2 appeared at 378.42℃. The structure of nanocrystalline TiO_2 was given by XRD pattern. TEM images show that the TiO_2 nanoparticles were sphere in shape, the size was less than 20nm,particle size distribution was in narrow range, and no agglomerates were observed.
