One step synthesis of highly active and selective epoxidation catalysts formed by organic–inorganic Ti containing mesoporous composites

Abstract

Ti-MCM-41 materials with methylated silicons have been prepared in one step synthesis; the resultant organic–inorganic composites are highly stable and present the highest activity and selectivity ever reported on Ti containing mesoporous catalysts for the epoxidation of olefins using organic peroxides.
