Patent ID: 7150861

Claim:
A catalyst for purification of exhaust gases, which is a catalyst for purification of CO-containing exhaust gases, comprising: a metal oxide as a support and a catalytic component A being supported thereon as a catalytic component and including at least one noble metal element selected from the group consisting of Pt, Pd, Rh, Ru, Ir, and Au, and a catalytic component B including at least one Group I to Group III metal elements as another catalytic component supported on the support; wherein the support includes, as the metal oxide, titanium oxide and/or a composite oxide of Ti and at least one metal element selected from the group consisting of Si, Al, W, and Zr and is a monolithically molded type porous honeycomb support which is obtained by a process including the steps of extrusion-molding and then calcining materials of the support; and wherein the catalytic component A is distributed with a quantitatively great inclination toward surfaces of the catalyst and said catalytic component B is distributed substantially evenly throughout the entire catalyst.
