Title: EXHAUST GAS PURIFICATION CATALYST
Abstract:
Provided is a novel exhaust gas purification catalyst that use a Cu delafossite oxide, the exhaust gas purification catalyst being capable of increasing the exhaust gas purification capacity compared to when Cu delafossite oxide is used alone. Proposed is an exhaust gas purification catalyst that contains a delafossite oxide represented by the general formula ABO2 and an inorganic porous material, wherein Cu is contained at the A site in the general formula for the delafossite oxide, one or more elements selected from the group consisting of Mn, Al, Cr, Ga, Fe, Co, Ni, In, La, Nd, Sm, Eu, Y, V, and Ti are contained at the B site, and Cu is contained at 3% to 30% of the total content (mass) of the delafossite oxide and the inorganic porous material.
