Amorphous alloy base catalyst, its preparation and its application

摘要

An amorphous alloy base catalyst containing boron consists of a porous support, an amorphous alloy Q-B and a metallic additive M. The preparation of the catalyst consists of contacting the porous support containing Q and the metallic element M with a solution of 0.5-10 M BH4-, in an initial atomic ratio of B/Q+M being 0.1-10 or preferably 1-4 and an initial atomic ratio of Q/ M in the porous support being 0.1-80 or preferably 0.5-20 at a temperature between the solidification temperature of the solution and 100 deg.C.
