Abstract

The fabrication of molybdovanadophosphoric acids incorporated into SBA-15 mesoporous silicas has been achieved via a one-pot procedure. The as-obtained composite materials were well characterized by XRD, TEM, and nitrogen adsorption–desorption which indicated that the composite materials possessed good mesoporous character. FT-IR, ICP showed molybdovanadophosphoric acids had been successfully incorporated into SBA-15 mesoporous silicas with intact structure of Keggin units. Due to well dispersion of the Keggin units, high structural stability, and low leaching level of active Keggin units, the obtained-catalysts systems showed significant catalytic efficiency and reusability for wet hydrogen peroxide oxidation of phenol.
