Abstract:		"In this work, a series of delta-MnO(2)/USY with different contents of delta-MnO(2) (0.3 wt%, 1.5 wt%, 3.0 wt%, 10.0 wt%, and 15.0 wt%) were prepared. In addition, their performances of the adsorption of toluene, degradation and mineralization of toluene, and removal of ozone (O(3)) were investigated. The results showed that, among all the samples, 3.0 wt% delta-MnO(2)/USY displayed the best performance of toluene adsorption, degradation and mineralization. Furthermore, according to the in situ DRIFTS and GC-MS analysis, the intermediate by-products during the toluene degradation progress were ascertained and the possible pathway of catalytic oxidation toluene by delta-MnO(2)/USY in the presence of O(3) was proposed"
