VIBRATIONAL SPECTROSCOPIC EVIDENCE FOR THE PRESENCE OF TiO₆ STRUCTURAL UNITS IN TITANOSILICATE MOLECULAR SIEVE ETS-10

A comparison of infrared and Raman spectra of a titanosilicate molecular sieve ETS -10 with literature data on titanium-containing ZSM-5 (TS-1) and perovskite SrTiO₃ provides conclusive evidence for the presence of intraframework TiO₆ octahedral units in ETS-10. The appearance of a very strong band at 723 cm^-1 in the Raman spectrum of ETS-10 suggests that the technique can be useful for the characterization of molecular sieves containing TiO₆ structural units.
