Outline of Final Research Achievements |
NOx, which is present in the exhaust gas of stationary emission sources, is removed by selective catalytic reduction with NH3 (NH3-SCR) over vanadium oxide-based catalysts according to the following equation: (4NO + 4NH3 + O2 → 4N2 + 6H2O). We have reported the photo-assisted selective catalytic reduction (photo-SCR) of NO with NH3 in the presence of O2 over TiO2 photocatalysts under UV-light irradiation. It was espected that various dye-modified photocatalyst work efficiently as a visible-light response photocatalyst in the gas phase. we investigated photo-SCR under visible-light irradiation using TiO2 photocatalysts modified with N3-dye to improve the activity of this photocatalytic system.
