摘要：
Preparation, characterization and catalytic application of a novel ordered mesoporous organosilica-titania with ionic liquid framework (ILNOS-Ti) is developed. The ILNOS-Ti was prepared by surfactant directed simultaneous hydrolysis and condensation of alkyl-imidazolium ionic liquid and tetramethoxysilane followed by treatment with tetra-tert-butylorthotitanate (TBOT) under moderate conditions. The chemical and physical properties of the material were investigated using TG, EDX, DRIFT, TEM, SEM, small angle XRD and nitrogen adsorption-desorption analyses. The ILNOS-Ti was applied as efficient nanocatalyst for the green oxidation of alcohols in the presence of hydrogen peroxide under mild conditions. The corresponding carbonyl products were obtained in high yield. The stability, recoverability and reusability of the designed nanocatalyst were also studied under applied reaction conditions.
