Research Abstract

Spherical titania nano particles, macroporous silica and titania were successfully prepared by using reverse micelles in non-aqueous solution as templates The non-aqueous reverse micelle systems were formed by the addition of the highly polar solvent into the anionic surfactant solution of the non-polar solvent. The hydrolysis reaction of metal alkoxide was retarded by controlling the water content in the non-aqueous reverse micelle systems, which lead to the prevention of the formation of amorphous metal oxide products.
