研究了Ｅｕ， Ｇｄ ，Ｔｂ 对化学还原法制备非晶态ＮｉＢ 合金催化剂的加氢及抗硫性能的影响。Ｅｕ ，Ｇｄ，Ｔｂ 的加入可提高ＮｉＢ合金的催化活性和抗硫性， 其原因是稀土元素与ＮｉＢ 合金间存在相互作用。ＮｉＢ合金催化剂的活性中心与还原态的镍及镍硼氧物种有关。
The effects of Eu, Gd and Tb on the hydrogenation and sulfur resistance of amorphous NiB alloy catalysts prepared by chemical reduction were studied. The addition of Eu, Gd and Tb can improve the catalytic activity and sulfur resistance of NiB alloy because of the interaction between rare earth element and NiB alloy. The active center of NiB alloy catalyst is related to reduced nickel and boron-oxygen species.
