摘要： A copper oxide based catalyst for dehydrogenation of cyclohexanol which is a copper oxide-zinc oxide based catalyst or a copper oxide-silicon oxide based catalyst further comprising one of palladium, platinum and ruthenium in a very small amount; and a method for preparing the copper oxide based catalyst which comprises combining the co-precipitation method or the kneading method and the spray method. The copper oxide based catalyst for dehydrogenation of cyclohexanol exhibits high activity and high selectivity, and thus may be used for producing cyclohexanone at a reduced reaction temperature and/or with an enhanced yield, as compared to a conventional catalyst.
