Zusammenfassung:	The carried Au catalyst has excellent low temperature activity, excellent steam and sulfur poison resistance and other features. It has Au as active component and formed Fe2O3 or other metal oxide ascarrier. Under the gas volume space rare of 1.5X103 /h-1, it can catalyze the oxidation of CO at normal temperature and normal humidity. In case of CO density of 1.0% in material gas, it may react for over 300 min with a CO penetrating rate lower than 94 ppm. The catalyst may be used in CO eliminator, such as gas mask or indoor air purification.
