Abstract:

The Ti-ZSM-11 zeolite was synthesized under hydrothermal condition. All samples of Ti-ZSM-11 showed an absorption at 960cm-1 - 980cm-1 in IR spectra, and the intensity of this band decreased with the increasing of the Si/Ti ratio. The IR spectra of TS-2 was compared with that of titanate, titania, amorphous silica and gel of reactant mixture. The resultes showed that this band was also observed in amorphous silica and gel of reactant mixture, but not found in titanate and titania. This characteristic absorption in TS-2 was assigned to a strectching of a [O3SiOTi] mode formed by a [SiO4] tetrahedral unit bonded to a Ti(Ⅵ) ion, and the position of this band was shifted with the different coordination circumstances of Ti atom.
