Preparation of Na no-sized TiO2 Particles by Microemulsion Method

摘要

Nano-sized titania particles have been prepared by hydrosis of tetrabutyl titanate in the droplet of water/surfactant/pentanoleptane microemulsion system. The effects of ingredient change on the particle size were investigated. The results show that TiCb was in the form of rutile after annealing. TiOs was characterized by DSC, FTIR, XRD and TEM to measure the transformation temperature, surface adsorption and average size. The photocatalytic performance of the prepared TiO_2 was also investigated in the photocatalytic process.
