To improve the capacity for complete oxidation of gaseous benzene by catalytic ozonation, a series of metal oxides catalysts (Mn, Co, Ni, Cu, Zn and Ce) were prepared by impregnation method using ZSM-5 zeolite as the support. The developed metal oxides were highly dispersed in nanosize on the support. Among them, MnO2/ZSM-5 showed the best activity toward catalytic ozonation of benzene. Benzene can be completely removed even at room temperature and CO2 selectivity reached 84.7%. MnO2/ZSM-5 was quite effective due to the production of highly reactive oxidizing species from ozone decomposition. The activities toward benzene catalytic ozonation are closely related to the capacity for ozone decomposition.
