The purpose of this study is to improve NOx removal by combining surface discharge and TiO2. Especially, this paper was discussed about the effect of TiO2 to NOx removal in case of mixing oxygen. The reactor had structure that luminescence of surface discharge was irradiated to TiO2. Therefore it was expected that TiO2 was activated by UV rays included in luminescence of surface discharge. TiO2 was used in the form of porous sheet mixed particle of Teflon and TiO2. The experiment was carried out to measure NOx concentration in case of changing discharge power and O2 concentration. As a result, NOx removal performance was improved by using TiO2. From this matter, it was found that TiO2 was activated by luminescence of surface discharge. In the effect of oxygen to TiO2, NOx removal of TiO2 increased with increasing O2 concentration. The reason is that the amount of O2- generated on TiO2 surface increases. From the point of by-product, NO2 was not generated in case of using TiO2. It was considered that generated NO2 by discharge was adsorbed to inside of TiO2 sheet that had porous structure.
