Catalyst for oxidizing carbon monoxide and method of manufacturing the same

摘要

A catalyst that oxidizes carbon monoxide includes a bimetal consisting of platinum and a transition metal in a bimetallic phase that is loaded on gamma-alumina support. The catalyst is manufactured by uniformly mixing a platinum precursor, a transition metal precursor, and gamma-alumina (gamma-Al₂O₃) in a dispersion medium to provide a mixture; drying the mixture; calcining the dried mixture; and reducing the calcined dried mixture. Since the catalyst that oxidizes carbon monoxide has high reaction activity even at low temperature and excellent reaction selectivity, and a methanation reaction and reoxidization do not occur, and the catalyst can effectively eliminate carbon monoxide in the fuel.
