CATALYST FOR CONVERSION NITROGEN OXIDES INTO AMMONIA AND MANUFACTURING METHOD FOR THE SAME

摘要

The object of the present invention is to provide a catalyst for converting nitrogen oxides into ammonia and a manufacturing method thereof, wherein the catalyst is capable of converting nitrogen oxides into ammonia under the condition of diluted exhaust gas with stoichiometric air-fuel ratio (A/F=14.7). To achieve the object, the catalyst for converting nitrogen oxides into ammonia according to the present invention includes a metal support with precious metal and is capable of converting nitrogen oxides into ammonia under the condition of diluted exhaust gas with stoichiometric air-fuel ratio (A/F=14.7).
