Carbon nanotubes supported NiB and Ni-M(x%)-B(M=Ag,Cu) amorphous alloy catalysts were prepared by the impregnation-chemical reductant method with the aid of ultrasonication.The experiments of acetylene) half-hydrogenation showed that an addition of 1% Ag to NiB/CNTs decreased considerably the hydrogenation) activity but enhanced the selectivity of ethylene.when doping Cu ranging from 3% to 5%,Ni-Cu-B/CNTs catalysts exhibited better catalytic activity and slightly higher ethylene selectivity.
