It discloses a catalyst and product manufacturing method and a purpose related to the containing palladium. Ceria-free oxygen first catalyst layer comprises the impregnated platinum onto the impregnated palladium and a refractory metal oxide on a storage component and formed on the base material, and impregnating the oxygen storage component of platinum and zirconia-coated or yttria- comprising a rhodium impregnated on an alumina coating, and discloses a catalytic article comprising a second catalyst layer formed on the first layer. Palladium component of the catalyst article is present at a higher rate compared to other platinum group metal component. Catalytic article in the exhaust gas, in particular a lean-rich provides after aging, improved reduction of NO
