The Effect of TiO2 Catalyst on Ozone and Nitrous Oxide Production by Dielectric Barrier Discharge

摘要

The aim of present study was to investigate the influence of oxygen percentage (1-80%), temperature (20 and 100 degrees C) and the addition of TiO2 catalyst on the production of ozone O-3 and nitrous oxide N2O by DBD. The production efficiency of O-3 increased with O-2 percentage while the production efficiency of N2O had a maximum at approximately 20% of O-2. The production of O-3 slightly decreased with the increase of temperature while the production of N2O increased. The presence of TiO2 considerably increased the production efficiency of N2O production. The O-3 production efficiency was enhanced by TiO2 at 20 degrees C and reduced at 100 degrees C.
