| Abstract: | Ti ZSM 5 zeolite has been prepared by gas soild isomorphous substitution using ZSM 5 as precursor synthesized with TEABr(tetraethylammonium bromide) template. XRD, FT IR, UV Vis, chemical analysis and XPS results show that Ti atoms are mainly tetrahedrally coordinated in the framework of Ti ZSM 5 zeolite and that titanium in the framework is enriched on the surface of crystal. Ti ZSM 5 zeolite has excellent catalytic property according to the results of hydroxylation of phenol with aqueous hydrogen peroxide. |
