Abstract
Disclosed is a catalyst for converting nitrogen oxide into ammonia, which is capable of converting nitrogen oxide into ammonia under fuel lean exhaust gas conditions of more than theoretical air-fuel ratio (A/F=14.7), and a method for manufacturing the same. The catalyst according to the present invention comprises a metal oxide support impregnated with a precious metal, such that conversion of nitrogen oxide into ammonia under fuel lean exhaust gas conditions of more than theoretical air-fuel ratio (A/F=14.7) is possible.
