Method for preparing oxidation catalyst and catalysts prepared by the method

Abstract

A method for preparing oxidation catalyst comprising cerium oxide and a metal selected from the group consisting of gold, platinum palladium, tin, ruthenium, or nickel by sputtering cerium oxide and a metal from a target to a substrate wherein the cerium oxide and a metal material are sputtered to the substrate concurrently from at least one target under an argon atmosphere to form a layer of cerium oxide including dispersed atoms of the metal Specific Au—CeO2 and Pt—CeO2 catalysts are prepared by using this method.
