摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control catalyst capable of maintaining high NOx cleaning ability over a long period of time which is adaptive to lean-burn conditions even if the amount of noble metals is reduced. SOLUTION: The exhaust emission control catalyst has a porous carrier and a catalytic active component carried on the porous carrier in a gas flow passage of an internal combustion engine wherein exhaust gas with a lean air-fuel ratio and exhaust gas with a rich or stoichiometric air-fuel ratio flow in. The catalytic active component contains: at least one kind selected from noble metal comprising Rh, Pt, Pd; at least one kind selected from an alkaline metal or an alkaline earth metal; and Ti. The total weight of Rh+Pt+Pd is 4 pts. wt. or less calculated as a metal element in regard to the 190 pts. wt. of the porous carrier. A noble metal exposing rate of the catalyst (noble metal exposing amount of the catalyst/noble metal amount contained in the catalyst×100) is 0.8% or more. COPYRIGHT: (C)2004,JPO
