CATALYST FOR PURIFICATION OF EXHAUST GASES AND PURIFICATION METHOD OF EXHAUST GASES USING THE SAME

摘要

PURPOSE: Provided is a catalyst for purification of CO-containing exhaust gases, which can achieve high purification efficiency without increasing the quantity of the supported noble metal as a catalytic component. Also, a purification method of CO-containing exhaust gases using the catalyst is provided. CONSTITUTION: The catalyst(10) comprises a metal oxide as a support and a catalytic component A being supported thereon as a catalytic component and including a specific noble metal element, wherein the support includes a titanium-containing oxide as the metal oxide and is a monolithically molded type porous honeycomb support(11) 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.
