| Research Abstract |
Catalytic properties of manganese oxides for benzene oxidation with ozone were compared with those of the oxides of metals in first transition series. SiO2-supported Mn oxides showed higher activity than other metal oxides. Ozone was efficiently consumed in catalytic oxidation of benzene. The most important steps in benzene oxidation with ozone are the formation and oxidation of byproduct compounds on catalysts formed in benzene oxidation. The byproduct compounds on Mn-oxide were rapidly oxidized to CO2and CO. On the other hand, Fe-, Co-, Ni-, and Cu-oxides suffered from catalyst deactivation due to the build-up of the byproduct compounds and their low activity for the oxidation of the byproduct compounds. Thus, the higher activity of Mn oxides for benzene oxidation is ascribed to the facile oxidation of the byproduct compounds on the catalysts.
