Abstract
A catalyst for purifying an exhaust gas comprising a carrier substantially composed of calcium aluminate and titanium oxide. The carrier is deposited with a platinum group metal or a metal oxide capable of oxidizing reductive gases into innoxious ones. The titanium oxide is applied on the surface of the carrier or incorporated in the carrier. The carrier may further comprise a transition metal oxide showing catalytic activity. A method of making a catalyst is also disclosed in which titanium oxide is applied on the surface of a solid mass of calcium aluminate.
