Abstract

In this study, we have demonstrated the significance of steric hindrance on the activity of a typical heterogeneous catalyst, Ni/Al2O3, for the hydrogenation of the biomass-derived furans. The nanofibrous Ni-Al2O3 catalyst, prepared via an electrospinning method, possessed a much lower specific area and nickel atom percentage on the surface than the amorphous Ni/γ-Al2O3 catalyst, but showed a much superior activity for the hydrogenation of the furans. At room temperature, the conversion of furfural reached 99.0% over the nanofibrous Ni-Al2O3, while the Ni/γ-Al2O3 catalyst showed negligible activity, originating from their varied steric hindrances of accessing the nickel sites by the organic feedstock.
