- This study focused on the volatile organic compounds (VOCs) abatement by catalytic combustion/adsorption over Rh-based/ZSM-5. A series of Rh-based catalysts were prepared by wet co-impregnation method and evaluated by toluene combustion. Rh 1 Cu 3 /ZSM-5 presented superb toluene catalytic activity, great long-run stability, and excellent catalytic adaptability to various VOCs. Besides, Rh 1 Cu 3 /ZSM-5 performed good toluene adsorption capability in the column breakthrough experiments. Characterization results indicated that the interaction between Rh species and Cu oxides increased the content of chemisorbed oxygen in lattice layer (O ads-chem ), which improved the catalytic performance efficiently. Moreover, Rh 1 Cu 3 /ZSM-5 showed excellent adsorption ability for toluene due to its large specific surface area, and the strong interaction between metal nanoparticles and VOCs molecules. Overall, this kind of bifunctional materials with dual-metal modification were significant for the development of VOCs abatement. Graphic Abstract
