Metal Molybdate Catalysts for the Selective Oxidation of Olefins and Alcohols Using Hydrogen Peroxide as Oxidant

Abstract

Several facile metal molybdates were prepared by hydrothermal method and characterized by X-ray diffraction (XRD). Meanwhile, the bimetallic combination effect of these metal molybdates as bimetallic catalysts applied to the selective oxidation of various olefins and alcohols was investigated. It was found that there was the existence of bimetallic combination effect and the combination of Co and Mo had benignant effect compared with the individual metal catalysts and other metal molybdates in the reaction of oxidizing olefins to aldehydes. This bimetallic catalyst also showed very prominent performance (selectivity is 100%) in the oxidation of the alcohols to corresponding carbonyl compounds. The combination of double metal provides a method for the catalytic oxidation of olefins and alcohols.
