Abstract
The efficiencies of TiO 2-based bulk and supported catalysts in the NO x (NO + NO 2) removal from flowing NO–O 2–N 2 mixture under UV irradiation are quantitatively assessed by measuring the outlet NO and NO 2 concentrations as a function of irradiation time. It is found that specific photocatalytic activity of TiO 2 in this process can be considerably enhanced by dispersing TiO 2 over high-surface alumina or by incorporating into TiO 2 alkaline additives (BaO, urea). Effect of platinum doping is dependent on the Pt oxidation state. The mechanism of NO photooxidation on TiO 2 and the role of OH radicals and O 2 −species in it are discussed.
