Biomass-derived carbon supported Ni catalyst: An effective heterogeneous non-noble metal catalyst for the hydrogenation of nitro compounds
There has been a great deal of attention in the development of heterogeneous non-noble metal catalysts for the selective and mild hydrogenation of nitro compounds into primary amines. Herein, the biomass-derived carbon material supported Ni catalyst (Ni/C) was facilely prepared by the one-pot pyrolysis process, and the as-prepared Ni/C catalyst demonstrated a high catalytic activity for the hydrogenation of nitro compounds into primary amines at room temperature. The Ni/C catalyst not only demonstrated a high catalytic activity, but also showed a good tolerance to other functional groups. Structurally-diverse primary amines were achieved in yields from 92% to 99% within a few hour at room temperature under 5 bar H2. Furthermore, the Ni/C catalyst showed a good reusability without the loss of its activity.
