1. An exhaust gas purification catalyst disposed in an exhaust gas channel of an engine and comprising a catalytic layer provided on a substrate, wherein
the substrate is a particulate filter, the catalytic layer contains multiple types of γ-aluminas which are different in composition, Pt loaded on the multiple types of γ-aluminas, a composite oxide which releases active oxygen, and Pt loaded on the composite oxide, and a total amount of Pt loaded on each of the multiple types of γ-aluminas is larger than a total amount of Pt loaded on the composite oxide. |
