| Abstract: | 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. |
