【Abstract】 Amorphous Ni-B、Co-B and Ni-Co-B alloys with different compositions have been prepared by chemical reduction method.The proper ties of alloys were examined by XRD and TEM methods and their compositi ons were analysed by ICP.DSC methods was used to examine the crystallization temperature of a morphous alloys.The results CO hydrogenation using amorphous alloys as catalysts showed that the thermal stability of catalysts depended on their composition and therefore affected the catalytic activity for CO hydrogenation.The higher the crystallization temperature of catalysts,the higher their activity for CO hydrogenation.更多还原
