Abstract
The Ni-B amorphous alloy catalyst with uniform particle was prepared by chemical reduction the nickel ethylenediamine complex over ultrasonic-assisted. The catalyst was characterized by XRD, TEM and H2-TPD techniques, and then evaluated activity by hydrogenation of glucose. Compared with the conventional Ni-B catalyst, the as-prepared Ni-B catalyst exhibited much higher catalytic activity. The results could be attributed to the higher dispersion, the stronger adsorption of hydrogen and the less aggregation of Ni active sites, which mostly result from the formation of the nickel complex and the effect of ultrasonic cavitation.
