| Popis: | International audience; Atmospheric Non-Thermal Plasma (ANTP) technology for indoor air treatment has the disadvantage to produce undesirable by-products such as ozone and NOx. To overcome the by-products formation and increasing energy efficiency, ANTP could take advantage of its synergetic effect through combination with heterogeneous catalysts. Various catalysts based on Ag, Au, Cu, Co, Mn, La (supported on OMS-2, Al2O3 or CeO2) and Nb has been investigated with and without a dielectric barrier discharge (DBD). In the absence of catalysts, the toluene removal efficiency was about 60% with O3, CO, CO2, and NOx as reaction products. Without plasma, the reaction of toluene conversion over Al2O3, OMS-2, and perovskite based catalysts are promoted only at high temperature (200-400°C). When the plasma was combined to catalyst at room temperature, the toluene removal efficiency strongly increased when the catalysts are in the discharge region. Best results, up to 96% toluene conversion, were obtained when using 1wt%Au/Al2O3 or Nb2O5 catalysts. The products of the toluene oxidation were CO and CO2. |
