  • Exhaust gas purification
    Patent number: 4478797
    Abstract: An oxidation catalyst for use in a catalytic exhaust gas purification unit comprises a substrate on which a refractory metal oxide is coated, a base metal component and one or more metals from the Platinum Group. The catalyst is highly effective when a metallic substrate is employed and the loading of the refractory metal oxide coating is relatively high. The base metal is useful for catalysts having a ceramic substrate and a relatively low coating loading.
