Nanofibers and amorphous Ni/Al2O3 catalysts — effect of steric hindrance on hydrogenation performance

The steric hindrance of nanofibrous Ni–Al₂O₃ catalyst can be effectively reduced compared with that of the amorphous Ni/γ-Al₂O₃ catalyst, which greatly increases the activity of furfural and HMF hydrogenation at room temperature.
