Abstract
The selective catalytic reduction of nitric oxide with propene and oxygen-containing organic compounds over several alumina-supported metal catalysts was investigated. Alumina-supported silver catalysts showed high activities in the presence of water and excess oxygen, while water vapor significantly decreased the activities of alumina and Co/Al 2O 3 which were highly active in the absence of water. It was also found that oxygen-containing organic compounds such as ethanol and acetone were more effective than propene in reducing nitric oxide over Ag/Al 2O 3 in the presence of water and excess oxygen.
