Abstract
The present invention provides a catalyst composition which can decompose an organic nitrogen compound at a relatively low temperature to convert the compound to Nand render it harmless in the purification of an exhaust gas containing the compound (nitrogen-based exhaust gas); a catalyst containing the catalyst composition; a method for producing the catalyst; and an exhaust gas purification apparatus containing the catalyst. By using a catalyst composition formed by mixing copper oxide particles and zeolite particles, an organic nitrogen compound and/or ammonia can be converted to Nhighly selectively. The catalyst composition of the present invention may further contain a manganese oxide and/or a precious metal.
