Title:
COMPOSITE CATALYST FOR REMOVING CARBON MONOXIDE AND METHOD FOR REMOVING CARBON MONOXIDE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/052536
Kind Code:
A1
Abstract:
A composite catalyst for removing carbon monoxide which comprises a gold nano-particulate catalyst comprising gold particles having an average particle diameter of 25 nm or less carried on a metal oxide and an alkaline porous material; and a method for removing carbon monoxide using the composite catalyst. The composite catalyst can be used for removing carbon monoxide over a wide range of the concentration of carbon monoxide from a low to a high concentration and is capable of maintaining high activity at an ordinary temperature for a long period of time, and thus can be advantageously used for removing carbon monoxide from a gas in a living space.
