Preparation of Nano-Sized TiO_2 Particles by Microemulsion Method

摘要

Nano-sized titania powders have been prepared by hydrolysis of tetrabutyl titanate in the droplet of water/OP-7/pentanol/cyclohexane microemulsion system. The effects of ingredient change on the water drop size and particle size were investigated. The prepared TiO_2 was in the form of anatase after annealing. TiO_2 was characterized by TG-TGA, FTIR, XRD to measure the transformation temperature, surface adsorption and average size.
