Abstract

The dielectric barrier discharge process combined with a TiO 2 photocatalyst was applied to remove NO and SO 2. The dielectric barrier discharge reactor was packed with glass beads as a dielectric material and the glass beads were coated with TiO 2 particles by dip-coating into solutions of TiO 2 particles prepared by using sol-gel method and of Degussa P-25 TiO 2 particles. The TiO 2 thin film dip-coated 1 time into the solution of TiO 2 prepared by using the sol-gel method was the most uniform and efficient for NO and SO 2 removal when using a dielectric barrier discharge photocatalyst hybrid system. The increase in the applied peak voltage enhanced the NO and SO 2 removal efficiencies. The NO and SO 2 removal efficiencies decreased as the initial NO and SO 2 concentrations were increased.
