Mesoporous stannosilicate molecular sieves with the MCM-41 structure have been synthesized by hydrothermal methods and characterized in detail by elemental analysis, XRD, N{sub 2} adsorption measurements, and UV-visible, IR, {sup 13}C CP/MAS NMR, {sup 29}Si MAS NMR, {sup 119}Sn MAS NMR, and Moessbauer spectroscopic methods. The increase in the unit-cell parameter (XRD), the presence of an absorption band at {approximately}208 nm (UV-vis), and Moessbauer 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 H{sub 2}O{sub 2}/tertiary butyl hydroperoxide.
