Abstract
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 carried 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.
