Abstract

In this research, since it aims to improve NOx removal rate, the system using discharge, photocatalyst(titanium oxide, TiO2) and UV Lamp as substitution for sunlight is discussed. NOx is also removed at TiO2 surface activated by irradiating UV rays of discharge luminescence and UV lamp in addition to NOx removal by electric discharge. As a result of experiment, NOx removal rate was improved. Moreover, TiO2 sheet was stuck on the inner wall of the outer glass tube, and a UV lamp was installed inside the inner glass tube. By using discharge, TiO2, and UV lamp, NO removal rate became higher than that of the other conditions. Since TiO2 was irradiated with UV rays of discharge luminescence and UV lamp, photocatalytic action was promoted. Therefore, it is considered that in addition to NOx removal by discharge, NOx was removed on TiO2 surface.
