| description | The invention belongs to the field of noble metal catalysts, relates to the technical field of application of regulation and control of crystal faces of noble metal catalysts in selective hydrogenation reaction, and particularly relates to a selective hydrogenation catalyst with a specific crystal face as well as a preparation method and application of the selective hydrogenation catalyst with the specific crystal face. Palladium is uniformly and discretely distributed on the surface of the spherical Al2O3-K2CO3 carrier in the form of two-dimensional nanosheets (Pd2D), the crystal face (111) is selectively exposed, and the mass percent of Pd in the carrier is 3-10%. The prepared catalyst is easy to synthesize, compared with a traditional Pd/C catalyst, the atom utilization rate of Pd is increased through the two-dimensional nanosheet structure of palladium metal, and the catalytic performance of the selective hydrogenation reaction of (2S)-4-dimethylaminomethylene methyl pyroglutamate is remarkably improved. |
