The amorphous alloy catalysts of Ni-B and Co-B were prepared by chemical reduction method.XRD and DSC methods were used to verify the amorphous state of Ni-B andCo-Band the content was analyzed by using inductively coupled plasma(ICP).The catalyticactivity for hydrogenation of CO on Co-B was higher than that of Ni-B.The chemisorptionof CO and H2 and their interaction on Ni(Co)-B werestudied by using TPD-MS.It wasfound that there were one or two kinds of sorption states on the two catalysts for H2 and COrespectively.The intensity and quantity of sorption states were different for different amorphous alloys.
