Abstract
Abstract CuO/KIT-6 catalyst was prepared by the excess impregnation method, and used for ethanol selective catalytic oxidation to produce acetaldehyde. The properties of the prepared CuO/KIT-6 catalyst were investigated by XRD and TEM. The results indicate that the synthesized CuO/KIT-6 catalyst still retains highly ordered mesoporous structure with well-dispersed CuO species. The CuO/KIT-6 catalyst shows predominant ethanol selective catalytic oxidation activities. The ethanol conversion and acetaldehyde selectivity of the CuO/KIT-6 catalyst at 275°C are 93.8% and 96.6%, respectively. The CuO/KIT-6 catalyst has high ethanol selective catalytic oxidation activity and acetaldehyde selectivity, which can be attributed to the highly ordered mesoporous structure and well-dispersed CuO species.
