| abstract |
The invention belongs to the field of catalysts, and relates to a composite hydrogenation catalyst and a preparation method and application thereof. The composite catalyst comprises a polymer matrix cross-linked by a polybasic acid and a metal active component, the polymer matrix is a polymer containing a nitrogen-containing heterocyclic side group, and the nitrogen atom in the nitrogen-containing heterocyclic side group has A lone pair of electrons, at least a part of the metal active component forms a coordination bond with the lone pair of electrons of the nitrogen atom. The composite catalyst of the invention has the advantages of simple preparation method, low energy consumption, high metal utilization rate and good selectivity when used in hydrogenation reaction. |
