Abstract
A layered composite oxide is provided which is excellent in oxygen ion conductivity and, is capable of effectively decreasing a PM oxidation temperature without using a noble metal such as platinum or the like. The layered composite oxide is used in an oxidation catalyst, DPF, a ternary catalyst, and a NOx purification catalyst. The layered composite oxide has a composition represented by the following formula (1), La1.5Sr1.5Mn2-yByO7 . . . (1) (wherein B represents Cu and/or Fe, and y satisfies 0<y≦0.2).
