In this study, the fundamental experiments were performed for catalytic oxidation of NO (50 ppm) on in the presence of ozone. The experiments were carried out at various catalytic temperatures () and ozone concentrations (50-150 ppm) to investigate the behavior of NO oxidation. The honeycomb type catalyst was rectangular with a cell density of 300 cells per square inch. Due to injection, NO reacted with to form , which was adsorbed at the surface. The excessive ozone was decomposed to onto the catalyst bed, and then that was reacted with to form . It was found that the optimal /NO ratio for catalytic oxidation of NO on was 2.0, and the NO removal efficiency on was 83% at . As a result, NO was converted mainly to .
