One-pot synthesis of Ni–NiFe2O4/carbon nanofiber composites from biomass for selective hydrogenation of aromatic nitro compounds

Abstract

Ni–NiFe₂O₄/carbon nanofiber (Ni–NiFe₂O₄/CNF) composite materials were synthesized by fast pyrolysis of the FeCl₃ and NiCl₂ preloaded biomass. The as-synthesized materials showed a favourable catalytic performance in the hydrogenation of aromatic nitro compounds with high yield and selectivity. The catalyst can be easily separated using a magnet and its catalytic activity remains almost unchanged after 7-time reuse.
