  • Preparation of cerium oxide-supported nano gold-silver catalysts and its application in carbon monoxide removal in air
    Patent number: 8987166
    Abstract: The preparation of bimetallic gold-silver cerium dioxide-supported catalysts and the process of oxidation of carbon monoxide (CO) in air to remove CO using the gold-silver cerium dioxide-supported catalysts are disclosed. The gold loading is between 0.5 and 5 wt. %. Gold and silver particle sizes are between 1 and 3 nm, and Au/Ag weight ratio is between 1 and 10. Oxidation of CO in air over these catalysts is carried out in a fixed bed reactor to remove CO.
