Abstract
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.
