Summary:Background: Designing high-selective and low-cost catalysts for the selective hydrogenation of nitriles to high
value-added amines is important and challenging.
Methods: Herein, a non-noble metal Cu@NC-ZrO
 2
catalyst was prepared by simple pyrolysis using PCN-222(Cu)
MOF as the precursor.
Significant findings: Under lower temperature pyrolysis, the small Cu nanoparticles (NPs) and abundant Cu-N
 x
active sites were uniformly embedded in the N-doped support and the produced catalyst retains the mesoporous
structure of PCN-222(Cu), which are beneficial for catalytic performance. The Cu@NC-ZrO
 2–600 catalyst was
found to be economic and efficient for the selective hydrogenation of benzonitrile to benzylamine, and the
selectivity and conversion can be up to 100% and 95%, respectively. Moreover, due to the encapsulation of Cu
nanoparticles in the support N-doped carbon matrix, this catalyst showed outstanding stability of resistance to
leaching.
