Beschreibung
Zusammenfassung:	Disclosed is a catalyst composition used for purifying an exhaust gas containing an organic nitrogen compound (a nitrogen-containing exhaust gas) which is able to decompose the compound at relatively low temperatures, thereby transforming it into harmless N2. Also disclosed are a catalyst containing such a catalyst composition, a method for producing such a catalyst, and an exhaust gas-purifying apparatus using such a catalyst. By using a catalyst composition obtained by mixing copper oxide particles with zeolite particles, organic nitrogen compounds and/or ammonia can be transformed into N2 highly selectively. The catalyst composition may further contain a manganese oxide and/or a noble metal.
