Abstract
An exhaust gas purification catalytic devicecontains Pt, Pd, and Rh as catalytic metals. The catalytic metal Pt is loaded on silica-alumina which serves as a support, and Pt-loaded silica-alumina obtained by loading the Pt on the silica-alumina is contained in a catalytic layer with which an exhaust gas contacts first.
