A preparation method of a Co@CM multi-channel ceramic catalytic membrane for hydrogenation of p-nitrophenol is provided. In the catalytic membrane, a multi-channel ceramic membrane is adopted as a substrate. A cobalt salt as an active component is loaded in situ on a surface and in pores of the multi-channel ceramic membrane through a forced circulation with the help of the excellent reduction and anchoring effects of dopamine (DA), and then subjected to in situ self-reduction through calcination to produce the Co@CM multi-channel ceramic catalytic membrane. The preparation method has the following advantages: Nano-scale Co particles are loaded instead of a precious metal on a multi-channel ceramic membrane, and the surface of the Co particles is wrapped by carbon and nitrogen, which can effectively inhibit the loss of Co particles during a reaction. In addition, there is no need to add an additional reducing agent during the reduction of Co.

A simple preparation method and use of a support of a catalyst for hydrogenation are provided. The support is prepared by a direct mixing method as follows: 2-methylimidazole is directly mixed with different cobalt sources, and then calcination and acid-washing are conducted. This method has advantages such as simple preparation process flow, short preparation cycle, low raw material cost, and high support output. A Pd@CN catalyst prepared from the support can exhibit a high catalytic activity when used in a reaction system for phenol hydrogenation to prepare cyclohexanone.
