Abstract
A supported amorphous alloy catalyst, which is supported on a macroporous carrier-expanded graphite. The catalyst contains a Ni—B amorphous alloy (5 to 50% by weight) and a transition inductive metal (0.1 to 10% by weight). The diameter of expanded graphite carrier particles is 80-800 μm. Its BET specific surface area is 10-100 m2/g. The catalyst is prepared by metal inductive electroless powder plating method which is easy to apply to industrial production. Ni—B clusters of prepared catalyst are well dispersed on the support. The catalyst shows high catalytic activity and good mechanical property, and is safe to use with low manufacturing costs.
