Abstract

The mesoporous TiO 2 with high heat stability is synthesized by a novel sol-gel process. The colloid and the powder are characterized by means of TEM, XRD, TG-DTA and FTIR. The effects of calcination temperature and aging time on the properties of the material are systematically investigated. The results show that nanocrystalline TiO 2 has four crystal phases(amorphous, anatase, anatase-rutile, rutile) at different calcination temperature. The nanoparticle mesoporous TiO 2 is of uniform and very fine network texture with the pore size of 3～4nm. And the mesoporous structure can be maintained after heat treatment at 500℃ for 1h. The optimal preparation condition for the high specific surface area product is 2 days aging and 400℃ calcination.
