Abstract

Magnetite-mesoporous silica nanocomposite was functionalized with molybdenum complex to achieve an easily recoverable heterogeneous catalyst for the epoxidation of olefins. Physicochemical characterization methods such as Fourier transform infrared and inductively coupled plasma optical emission spectroscopies, X-ray diffraction, vibrating sample magnetometry, and transmission electron microscopy confirmed the immobilization of molybdenum complex on the surface of the magnetite-mesoporous silica nanocomposite. This supported molybdenum catalyst showed high catalytic activity and selectivity (> 99%) toward the epoxidation of olefins and was readily separated from the reaction mixture by an external magnet for employing in the next epoxidation reactions. The prepared catalyst showed reusability for three times without significant loss of its efficiency.
