摘要： A material having ultrafine gold particles immobilized thereon consists essentially of at least one support selected from the group consisting of metal oxides, metal sulfides, and carbonaceous substances and ultrafine gold particles having a maximum particle diameter of 250 angstroms and deposited on the support with strong interaction. The material exhibits high activity as a catalyst for the oxidation of carbon monoxide to carbon dioxide. It is produced by causing a vaporized organic gold complex to contact at least one support selected from the group consisting of metal oxides, metal sulfides, and carbonaceous substances in an atmosphere of reduced pressure thereby inducing adsorption of the vapor of organic gold complex on the support and then heating the product of the adsorption to a temperature in the range of 100.degree.-700.degree.
