Cobalt-manganese double metal catalyst for cyclohexane selective oxidation, preparation method and application

The invention discloses a cobalt-manganese double metal catalyst for cyclohexane selective oxidation, a preparation method and an application. The catalyst is a loaded catalyst, wherein the carrier which is a mesoporous material loads manganese nitrate and cobalt nitrate, the loading amount of cobalt nitrate is 1.0-6.0wt% and that of the manganese nitrate is 0.5-5.0wt%. The preparation method comprises the following steps: dissolving manganese nitrate and cobalt nitrate in a mixed solution of water and ethanol containing pyridine and adding the mesoporous material in a stirring condition; andthen drying the mixture overnight and calcining the same to obtain the cobalt-manganese double metal catalyst. The cobalt and manganese mixed catalyst is applied to a multiphase catalytic reaction forpreparing cyclohexanol and cyclohexanone by cyclohexane selective oxidization for the first time. The catalyst shows excellent activity and high selectivity, and has good stability. 本发明公开了种用于环己烷选择性氧化的钴锰双金属催化剂、制备方法和应用。其为负载型催化剂
