摘要：
The promoting effects of Mo on both the catalytic activity and the thermal stability of the Ni-B amorphous alloy were investigated. It was found that Mo dopant can strengthen the thermal stability and increase the activity of Ni-B amorphous alloy used in 2-ethylanthraquinone hydrogenation. It was suggested that the structural effects of Mo dopant, improve the thermal stability, effectively disperse the surface Ni atoms, increase the amounts of hydrogen adsorbed and thereby enhance the catalytic activity. However, over-much Mo addition was found to detrimentally cover some of the surface active Ni atoms, hence, leading to lower catalytic activity.
