Abstract: The heteropolyacid H6PMo9V3O40 (HPA) was encapsulated in MCM-41 and VPI-5. When HPA/MCM-41 is used in the direct oxidation of benzene to phenol, the heteropolyacid leaches from the MCM-41 and oxidation takes place in the homogeneous phase. VPI-5 retains the HPA and palladium acetate more efficiently than MCM-41, and can be used as a heterogeneous oxidation catalyst for benzene. However, its activity is very low since only the active species at the pore entrances of VPI-5 are accessible to the reactants.
