ABSTRACT:
The catalyst for the purification of exhaust gas in the form of monolithically-constructed catalyst with a catalyst component-loaded layer contains at least palladium and metallic aluminate powder as catalyst components, which metallic aluminate powder containing at least one element selected from the group consisting of cobalt, nickel and zinc. The method of manufacturing the catalyst for the purification of exhaust gas is characterized in that an alumina composite oxide is obtained by dissolving or dispersing fine grain alumina hydrate colloid and a water-soluble salt of at least one selected from the group consisting of cobalt, nickel and zinc into water, drying it by removing water, and then conducting calcining thereof.
