Removal of Toluene by Dielectric Barrier Discharge Combined with Modified Photocatalyst

Abstract:

The toluene being removed by dielectric barrier discharge (DBD) combined with modified photocatalyst was studied in the paper. Transition metal manganese was doped into crystal lattice of TiO₂ in order to improve the activity of photocatalyst, and the optimal doping ratio was confirmed in the study. As one of main factors, the influence on toluene removal efficiency of gas flow rate, initial concentration and electric field intensity was analyzed in the study. Furthermore, the energy efficiency was another important index which had been compared amongγ-Al₂O₃, TiO₂/γ-Al₂O₃ and Mn-TiO₂/γ-Al₂O₃. The result of study showed that DBD combined with Mn-TiO₂/γ-Al₂O₃ had the best buffer action against increasing of gas flow rate and initial concentration, the energy efficiency had the tendency as Mn-TiO₂/γ-Al₂O₃ > TiO₂/γ-Al₂O₃>γ-Al₂O₃, and the optimal doping ratio of manganese was 0.01.
