摘要：

Nanocrystalline anatase powders with particle sizes from 8 to 38 nm have been synthesized by hydrothermal treatment of aqueous TiOSO4 solutions and TiO2.nH(2)O amorphous gel. The products have been characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), and BET method.
