Benzene Oxidation with Ozone Over MnO(x)/MSU-H and MnO(x)/Mesoporous-SAPO-34 Catalysts.

Two mesoporous silica materials, MSU-H and mesoporous SAPO-34 (Meso-SAPO-34), were applied to the catalytic oxidation with ozone of benzene. The catalysts were characterized by X-ray diffraction, N2 adsorption-desorption, Brunauer-Emmett-Teller specific surface area, and H2-temperature programmed reduction. When MnO(x)/MSU-H was used at three different temperature, 50 degrees C, 80 degrees C, and 100 degrees C, the ozone conversion and CO(x) yield increased with increasing temperature.
