The invention belongs to the field of catalyst preparation, and particularly relates to an application and a preparation method of a bimetallic catalyst for synthesizing dimethyl 1,2-cyclohexanedicarboxylate from dimethyl phthalate. An M-Ni / nitrogen-doped carbon nanotube (M=Ru, Pd) bimetallic catalyst is prepared by taking a nitrogen-doped carbon nanotube as a dispersing agent and a carrier and utilizing a couple replacement method. The catalyst prepared by the method has the advantages of large specific surface area, high mechanical strength, small mass transfer limit, more uniform dispersion of active components on the surface of the carrier and the like; the preparation method is simple and easy to implement, high in operability, available for batch preparation and small in environmental pollution, and the catalyst can be used in a reaction for hydrogenation synthesis of dimethyl 1,2-cyclohexanedicarboxylate from dimethyl phthalate; and the reaction activity of the catalyst and the selectivity of dimethyl 1,2-cyclohexanedicarboxylate are obviously improved.
