Abstract

To provide insight into the mechanism of plasma catalytic oxidation of adsorbed benzene in a cycled storage–discharge (CSD) plasma catalytic process, ozone catalytic oxidation (OZCO) of adsorbed benzene over the AgMn/HZSM-5 (AgMn/HZ) catalyst at room temperature was studied. The properties of the AgMn/HZ catalyst were compared with those of HZ, Mn/HZ, Ag/HZ catalysts in investigations of the TPD of adsorbed benzene, the product distribution and O3 decomposition in OZCO of adsorbed benzene, and TPO and TPD of the used catalysts. For the AgMn/HZ catalyst, the adsorption capacity and the adsorption strength of benzene were significantly improved as compared to HZ, Ag/HZ and Mn/HZ. Adsorbed benzene is oxidized completely to CO2 by O3 catalyzed by Ag on HZ. MnOx, on the other hand, further speeds up the OZCO rate of benzene adsorbed on Ag/HZ.
