Preparation of chemoselective hydrogenation catalyst containing both CoNx and CoyZnS supported on N-doped porous carbon (CoNx-CoyZnS@NPC-Z) was reported. The CoNx-CoyZnS@NPC-Z catalyst were prepared by pyrolyzing the protein-metal-ion networks, followed by treatment with acid. The CoNx-CoyZnS@NPC-Z-3 catalyst delivered high catalytic activity and selectivity in chemoselective hydrogenation of nitroarenes afforded aryl amines R-NH2 [R = Ph, 4-ClC6H4, 2-naphthyl, etc.] with almost full conversion and >98% selectivity in water/methanol mixture solvents at 90¡ãC under 5 bar of H2 pressure for 3h of reaction. Also Schiff-base derivatives R1CH=NR2 [R1 = Ph, 4-ClC6H4, 4-MeOC6H4, etc.; R2 = Ph, 2-MeC6H4, 4-ClC6H4, etc.] were prepared via one-pot reductive amination of aryl aldehydes with aromatic nitro compounds using CoNx-CoyZnS@NPC-3 catalyst. Notably, the catalytic hydrogenation could work even under 1 bar of H2 pressure and at room temperature with high conversion and selectivity. Besides, CoNx-CoyZnS@NPC-Z-3 exhibited remarkable tolerance to CO or H2S poisoning and acid erosion.
