Abstract
The present invention provides an exhaust gas purification catalyst having an excellent purification performance for purifying chemically stable methane. A catalyst material 30 includes a carrier 32 formed of alumina and a catalyst 34 formed of at least one of palladium and a palladium oxide directly supported on the carrier 32. A specific surface area of the carrier 32 is preferably 20 m2/g or more 90 m2/g or less. In one preferred aspect, a proportion of Pd(100) and PdO(101) in crystal planes of the catalyst 34 at a joint surface between the catalyst 34 and the carrier 32 is 20 number % or more.
