In this research, synthesis of silicalite containing small amount of molybdenum is described. Characterization of this zeolite was carried out with Fr-IR, atomic absorption spectroscopy, X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). In order to increase molybdenum content in zeolite structure with grafting method, the prepared silicalite-1 underwent reaction with molybdenum hexacarbonyl at high temperature. The incorporation of molybdenum in the structure was increased to 11%. The modified zeolite catalyzed the epoxidation of olefins (cyclohexene and trans-2-hexene-1-ol) with about 90% yield and 98% selectivity. (C) 2002 Elsevier Science B.V All rights reserved.
