ABSTRACT:
An amorphous alloy catalyst containing nickel and phosphorus comprising a porous carrier, a Ni--P amorphous alloy supported on the carrier, and a pre-supported catalytic component for inducing and catalyzing the formation of the Ni--P amorphous alloy onto the carrier. In a preferred embodiment, the catalyst contains 0.15-30 wt % of Ni, based on the total weight of the catalyst, 0.03-10 wt % of P, based on the total weight of the catalyst, 0.01-3.5 wt % of B, based on the total weight of the catalyst. The nickel exists in the form of Ni--P or Ni--B amorphous alloy, the atomic ration Ni/P in the Ni--P amorphous alloy is in range of 0.5-10, the atomic ratio Ni/B in the Ni--B amorphous alloy is in range of 0.5-10. The catalyst may further comprise from 0.01 to 20 wt % of a metal additive (M), based on the total weight of the catalyst. The metal additive (M) refers to one or more metal elements, except Ni, which can be reduced from the corresponding salt into its elemental form.
