Abstract
An exhaust gas purifying catalyst includes: a composite oxide represented by: (AMM') (SiN)O. A is a cation of at least one of La and Pr; M is a cation of at least one of Ba, Ca, and Sr; M′ is a cation of at least one of Nd, Y, Al, Pr, Ce, Sr, Li, and Ca; N is a cation of at least one of Fe, Cu, and Al. The following are satisfied: 6≦a≦10, 0<w<5, 0≦x<5, 0<w+x≦5, 0≦y≦3, 0≦z≦3, A≠M′, and x≠0 when A is a cation of La. A noble metal ingredient which forms a solid solution with the composite oxide or is supported on the composite oxide, and an exhaust gas purifying catalyst product formed of a carrier made of a ceramic or metallic material, and a layer of the exhaust gas purifying catalyst supported on the carrier.
