| abstract |
The invention relates to a novel catalyst having excellent activity and selectivity for reducing nitric oxides (NO/NO 2 ) to nitrogen gas (N 2 ) with hydrogen (H 2 ) being used as a reducing agent under strongly oxidizing conditions (e.g., 2-10 vol % O 2 ) (H 2 -SCR) in the 100-400° C. range, but in particular to the low-temperature range 100-200° C. The inventive catalyst is a combination of platinum and palladium which are in contact with solid phases of a mixed MgO and CeO 2 medium. |
