An Fe-modified Co-B/carbon nanotubes (CNTs) amorphous alloy catalyst (Fe-Co-B/CNTs) with the Co-B particles loaded inside of the CNTs was prepared by chemical reduction. The effect of Fe on the structure, thermal stability and electronic characteristics of the Fe-Co-B/CNTs was studied by BET, ICP, XRD, DSC, XPS and H-2-TPD. The hydrogenation of m-chloronitrobenzene (m-CNB) to m-chloroaniline (m-CAN) over Co-B/CNTs and Fe-Co-B/CNTs was investigated. The Fe-modified Fe-Co-B/CNTs significantly improved the m-CNB hydrogenation activity and enhanced the selectivity for m-CAN compared with Co-B/CNTs (reaction rate from 7.49 to 10.44 mmol g(-1) h(-1) and selectivity from 93.4 to 96.9%). The addition of Fe in the Fe-Co-B/CNTs can improve the thermal stability of the amorphous alloy, promote the formation of active centers and enhance the electron interactions.
