Toluene abatement through adsorption and plasma oxidation using ZSM-5 mixed with γ-Al2O3, TiO2 or BaTiO3

[Display omitted] •ZSM-5 combined with γ-Al2O3, TiO2, and BaTiO3 were used for toluene removal.•A high mineralization rate of toluene was observed for ZSM-5-BaTiO3.•The utilization of Mn-Ag/ZSM-5-BaTiO3 catalysts reduced the byproducts O3 and N2O.•Discharge characteristics greatly influenced on plasma oxidation. Toluene abatement through adsorption and then plasma oxidation using ZSM-5, ZSM-5-γ-Al2O3 (Z-Al), ZSM-5-TiO2 (Z-Ti), ZSM-5-BaTiO3 (Z-Ba), and AgMn/ZSM-5-BaTiO3 (AgMn/Z-Ba) as adsorbents/catalysts was investigated. The efficiency of toluene removal reached ∼100% for all the tested adsorbents/catalysts. ZSM-5 had the lowest mineralization rate (MR) of ∼43%, while Z-Ba had the highest MR (88%) with an SCO2 of ∼80%. After loading AgMn onto Z-Ba, both the breakthrough capacity of toluene and SCO2 was increased, while the production of byproduct O3 and MR was decreased. The mixed materials created a higher amount of active species capable of deeply oxidizing adsorbed toluene.
