Abstract

Abstract

Mesoporous TiO₂ was prepared by a sol-gel method with the assistance of cetyl trimethyl ammonium bromide(CTAB).Then the activity of the photocatalyst so produced for photocatalytic decolorization of methyl orange(MO)solution was evaluated,and the photocatalyst was characterized with BET specific surface.The results indicate that with the ratio of n_CTAB to n_TBOT at 1:4 and calcination temperature at 450℃,mesoporous TiO₂ can be obtained.In addition,the activity of TiO₂ prepared in our experiments for photocatalytic decolorization of methyl orange is two times that of the TiO₂ commercially available.
