A novel preparation method for nanocrystalline titanium dioxide (TiO2) was introduced in this paper. We prepared a new aqueous peroxotitanale solution using H2TiO3, ammonia and H2O2 as starting materials. Amorphous precursor powder with different morphology was formed at near room temperature, which was transformed to anatase after annealing at 300degreesC followed by rutile at 850degreesC. This method is simple, environmental friendly and promising to be used for TiO2 synthesis. (C) 2004 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
