Abstract

The invention relates to a nitrogen-doped carbon supported ruthenium monatomic catalyst which is characterized by comprising a carrier and an active component supported on the carrier, wherein the carrier is nitrogen-doped carbon, and the active component is a metal ruthenium single atom; and the mass percentage of the metal ruthenium single atoms in the nitrogen-doped carbon-loaded ruthenium single atom catalyst is 0.01-1.2%. The catalyst takes nitrogen-doped carbon as the carrier and the metal ruthenium single atoms as the active component, and compared with the prior art, the catalyst can greatly improve the utilization rate of precious metal ruthenium in the reaction of preparing alicyclic amine through one-step hydrogenation of a nitro aromatic compound, does not introduce an alkalineauxiliary agent, and does not need subsequent separation operation. The production cost is greatly reduced, and the high-activity and high-selectivity one-step hydro-conversion of the nitro aromaticcompound into alicyclic amine is realized under mild conditions.

Description

technical field

[0001] The invention belongs to the technical field of catalysts, in particular to a nitrogen-doped carbon-supported ruthenium single-atom catalyst and its preparation method and application, especially to a nitrogen-doped carbon used for one-step hydrogenation of nitroaromatic compounds to prepare alicyclic amines Supported ruthenium single-atom catalyst and its preparation method and application. Background technique

[0002] Alicyclic amine is an important organic intermediate, which is widely used in rubber synthesis additives, heavy-duty anti-corrosion coatings, dyes, plastics, resin synthesis and other fields. Compared with aromatic amines, alicyclic amines do not contain benzene rings and are not easily oxidized. Products made of alicyclic amines are not easy to turn yellow, are resistant to aging, and have excellent performance. At present, alicyclic amines are mainly prepared by hydrogenation of corresponding aromatic amines. For example, cyclohexy...
