More Information
Summary:This invention declares the preparation of manganese-ceria-supported nano gold catalysts and the process of carbon monoxide preferential oxidation with rich-hydrogen to form carbon dioxide using manganese-ceria-supported nano gold catalysts. The gold particle size was less than 5 nm and supported on different molar ratio of mixed oxide MnO2-CeO2. Preferential oxidation of CO in hydrogen stream over these catalysts was carried out in fixed bed reactor. The O2/CO ratio should be between 0.5 and 2. Catalysts of this invention were applied in removing CO in fuel cell to prevent from poisoning of the electrode of fuel cell.
