The effect of rare earths(Sm,Pr,Ce,Nd and La)on the hydrogenation properties of p-chloronitrobenzene(CNB)over Pt/CNTs catalyst was studied in ethanol at 303 K and normal pressure.The results exhibited that the hydrogenation of p-CNB could be carded out over PtMOx/CNTs catalysts.Both catalytic activities and yields of p-chloroaniline(CAN)were all improved.PtCeOx/ CNTs catalyst exhibited the best catalytic activity(TOF was 0.47 s~(-1))and the highest yield of p-CAN(97.5 mol%).PtCeOx/CNTs (1.0 wt%)catalyst exhibited good stability on the hydrogenation of p-CNB.
