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.

Amorphous alloy catalyst containing phosphorus, its preparation and use

The present invention discloses an amorphous alloy catalyst containing boron, which is composed of a porous carrier, a Q-B amorphous alloy, and a metal additive (M), the content of Q-B amorphous alloy together with metal additive is from 0.1 to 60 wt %, based on the total weight of the catalyst, in which the atomic ratio (Q+M)/B is 0.5-10, and the Q/M atomic ratio is 0.1-1000; wherein Q represents an metal selected from group VIII and B represents boron; and said metal additive (M) refers to those one or more metal elements which can be reduced to its/their elemental states from the corresponding salts by a solution containing BH.sub.4.sup.- with the exception that M is not the one which is used as Q. Said catalyst exhibits high catalytic hydrogenation activity.
