摘要
A series of Pt-CeTi/ZSM-5 catalysts (0.5 wt % Pt) with different CeO2-TiO2/ZSM-5 mass ratios were synthesized and used for the catalytic oxidation of 1,2-dichloroethane and benzene. The results reveal that the strong Pt/CeO2-TiO2 interaction can be evidently enhanced by introducing proper amounts of CeO2-TiO2 mixed oxides, resulting in the improvement of Pt dispersion and redox properties as well as the production of more defective oxygen and Pt2+ species. The synergistic effect between abundant ZSM-5 acid sites (especially strong acid sites) and strong Pt/CeO2-TiO2 oxidizing sites facilitates the deep oxidation of benzene, intermediates, and byproducts generated from the 1,2-dichloro-ethane oxidation process at lower temperature. Among the catalysts, Pt-CeTi/ZSM-5(1/10) with the CeO2-TiO2/ZSM-5 mass ratio of 1/10 exhibits the greatest activity for benzene and 1,2-dichloroethane oxidation, showing the T90% of 145 and 245 degrees C, respectively. Moreover, the catalyst also possesses satisfactory adaptability for the oxidation of various VOCs and durability for 1,2-dichloroethane oxidation.
