Abstract

Mesoporous stannosilicate molecular sieves with the MCM-41 structure have been synthesized by hydrothermal methods and characterized in detail by elemental analysis, XRD, N2 adsorption measurements, and UV-visible, IR, 13C CP/MAS NMR, 29Si MAS NMR, 119Sn MAS NMR, and Mössbauer spectroscopic methods. The increase in the unit-cell parameter (XRD), the presence of an absorption band at ∼208 nm (UV-vis), and Mössbauer spectroscopy suggest the incorporation of Sn into the MCM-41 structure. The Sn-MCM-41 samples catalyze the selective oxidation/epoxidation of organic compounds by aqueous H2O2/tertiary butyl hydroperoxide.
