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.
