An amorphous NiB/SiO 2 catalyst, prepared by a reductive–impregnation method, was thoroughly studied as to its behavior in air and in benzene hydrogenation in a fixed‐bed reactor at atmospheric pressure. The results showed that the amorphous NiB/SiO 2 catalyst possessed long life and excellent resistance to aerial oxidation. Even after calcination at 400 °C, TP‐XRD and TPR measurements revealed that the amorphous NiB/SiO 2 catalyst was not oxidized, and could retain its activity in benzene hydrogenation.
