Abstract
Disclosed is an exhaust gas purifying catalyst which includes barium hexaaluminate, and palladium and barium which are supported on barium hexaaluminate, wherein the amount of supported palladium, as reduced to metallic Pd, is 0.2 to 3.5 mass % with respect to the mass of barium hexaaluminate; the amount of supported barium, as reduced to BaO, is 1 to 20 mass % with respect to the mass of barium hexaaluminate; and the ratio by mole of supported barium to supported palladium, Ba/Pd, is (0.5 to 10)/1; an exhaust gas purifying catalyst product which has a catalyst support made of a ceramic or metallic material, and a layer which is formed of the exhaust gas purifying catalyst as a predominant component and which is supported on the catalyst support; and a method for producing the exhaust gas purifying catalyst product.
