Abstract

In this work, a series of δ-MnO₂/USY with different contents of δ-MnO₂ (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 (O₃) were investigated. The results showed that, among all the samples, 3.0 wt% δ-MnO₂/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 δ-MnO₂/USY in the presence of O₃ was proposed.
