中文摘要:
      首次将非晶合金 (Ni B、 Ni P和 Ni BP)催化剂用于对 -乙基苯甲酸的加氢反应 ,获得了较好的实验结果 .几种催化剂的加氢活性顺序为 :Ni B >Ni BP>Raney Ni>Ni P.Ni B和 Ni P表面 Ni的电子状态不同 ,Ni B中 Ni呈现富电子状态 ,而在 Ni P中 Ni为缺电子状态 ,它们不同的电子状态导致了其催化活性的差异 .
英文摘要:
      Three kinds of alloy nickel based catalysts (NiB, NiP and NiBP) were prepared by chemical reduction, and their catalytic activities for the hydrogenation of 4\|ethyl benzoic acid were firstly investigated. The results showed that their catalytic activity sequence was NiB > NiBP > Raney Ni > NiP. The nickel in the amorphous alloy NiP exists in electron\|deficient state, while the nickel in NiB is inverse. The electronic states of nickel in NiB and NiP resulted in the difference of their catalytic activities for hydrogenation of 4\|ethylbenzoic acid.
