摘要：In this article a new method with urea as precipitant is adopted in the preparation of ultra-fine supported gold catalyst with satisfactory results. The gold particles thus obtained have an average particle diameter of about 4 nm. Au/Co3O4 (5 wt.%) catalyst is applied in the selective catalytic oxidation (SCO) of NO in simulated flue gases with satisfactory sulfur resistance, water resistance and low-temperature activity.
