Preparation of TiO2 Nanometer Powders
单分散纳米二氧化钛的研制

Monodisperse controllable TiO2 nanoparticles were prepared by using the hydrolysis of metal alkoxides(titanium tetrabutoxide) and modification of surface of particles in alcohol solution. The effect of reactive condition including reactant concentration, reactant time and solvent was studied in detail. The properties of particles were analysised by TEM, IR and so on. The experimental results show that TiO2 particles prepared are amorphous, well dispersed, and their particle sizes vary from 50 to 300nm along with the change of reactive conditions.
