摘要：
A catalyst comprising an iridium supported on at least one carrier selected from the group consisting of metal carbides and metal nitrides for eliminating nitrogen oxides in exhaust gas in the presence of oxygen in excess of the stoichiometric quantity of oxidizing components for reducing components. The catalyst is effective for eliminating NO.sub.x in exhaust gas from lean burn engines such as lean burn gasoline engines and diesel engines containing excess O.sub.2 corresponding to an A/F ratio of 17 or over.
