Ambient-Temperature Reductive Amination of 5-Hydroxymethylfurfural Over Al 2 O 3 -Supported Carbon-Doped Nickel Catalyst
An efficient catalytic system for the conversion of 5-hydroxymethylfurfural (HMF) into N-containing compounds over low-cost non-noble-metal catalysts is preferable, but it is challenging to reach high conversion and selectivity under mild conditions.

Summary: | An efficient catalytic system for the conversion of 5-hydroxymethylfurfural (HMF) into N-containing compounds over low-cost non-noble-metal catalysts is preferable, but it is challenging to reach high conversion and selectivity under mild conditions. Herein, an Al
O
-supported carbon-doped Ni catalyst was obtained via the direct pyrolysis-reduction of a mixture of Ni
(BTC)
⋅ 12H
O and Al
O
, generating stable Ni
species due to the presence of carbon residue. A high yield of 96 % was observed in the reductive amination of HMF into 5-hydroxymethyl furfurylamine (HMFA) with ammonia and hydrogen at ambient temperature. The catalyst was recyclable and could be applied to the ambient-temperature synthesis of HMF-based secondary/tertiary amines and other biomass-derived amines from the carbonyl compounds. The significant performance was attributable to the synergistic effect of Ni
species and acidic property of the support Al
O
, which promoted the selective ammonolysis of the imine intermediate while inhibiting the potential side reaction of over-hydrogenation. |
