Abstract
[Problem] The present invention provides a NOpurification catalyst which utilizes Ag as one of the catalyst components and exhibits NOpurification performance without adjustment to a special exhaust gas composition, as well as a method of producing the same. [Means for Solution] The present invention provides a nitrogen oxide purification catalyst in which particulates are supported on a metal oxide carrier, wherein the aforementioned particulates consist of Ag and Ni and the aforementioned Ag and Ni are at least partially alloyed. Also provided is a method of producing the aforementioned catalyst, comprising the step of preparing a colloidal suspension in which the ratio of Ag is 10 to 90 at % with respect to the total amount of Ag and Ni.
