The Catalytic Activity and Selectivity of Some Metallic Glasses in the Hydrogenation of 1-Hexene

Abstract

Abstract The catalytic activity and selectivity of twenty one amorphous alloy ribbons were examined in the hydrogenation of 1-hexene. The amorphous alloys are of higher activity but of similar hydrogenation selectivity to the crystalline ones. Pd-based amorphous alloy ribbons, in particular Pd80Si20, are of a relatively high catalytic activity and of low selectivity towards hydrogenation. Fe20Ni60P20 amorphous alloy is a highly hydrogenation selective catalyst. Incorporation of Pd in the Fe–Ni–B alloy doubled its activity and reduced its hydrogenation selectivity by 30%. Alloying P, instead of B, with Fe and Ni significantly increased the hydrogenation selectivity of this Fe–Ni based alloy; the hydrogenation selectivity was increased from 85% for Fe20Ni60B20 to 93% for Fe20Ni60P20.
