摘要：

Titania was impregnated on MCM-41 mesoporous material by the liquid-phase reaction of titanium butoxide followed by washing and calcination. The impregnated titania was highly dispersed on the pore wall with tetrahedral coordination. The impregnating amount of titania was considerably larger than 23%, and produced the peroxo radical upon the addition of hydrogen peroxide.
