摘要：
It is an object of the present invention to provide a catalyst for the exhaust gas purification having excellent ignition performance and NOx purification performance. The present invention provides a catalyst for the exhaust gas purification which comprises a catalytically active component (I) having palladium and barium supported on a refractory inorganic oxide (A); and a catalytically active component (II) having at least either of rhodium and platinum on a refractory inorganic oxide (B), a method for the production thereof, and a method for purifying an exhaust gas using such a catalyst.
