CATALYST FOR CARBON MONOXIDE REMOVAL AND METHOD OF REMOVING CARBON MONOXIDE WITH THE CATALYST

摘要

A method of efficiently removing carbon monoxide over long in which both carbon dioxide and water are removed from a gas to be treated to thereby effectively inhibit a gold nanoparticle catalyst from being deactivated. Also provided is a catalyst for carbon monoxide removal which comprises: a gold nanoparticle catalyst comprising a metal oxide and deposited thereon gold particles having an average particle diameter of 25 nm or smaller; and an agent for the removal of carbon dioxide and water. The method for removing carbon monoxide from a gas containing carbon monoxide is characterized by treating a gas containing carbon monoxide with a gold nanoparticle catalyst comprising a metal oxide and deposited thereon gold particles having an average particle diameter of 25 nm or smaller and with an agent for the removal of carbon dioxide and water.
