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.
