Abstract
Hydrogenation properties of p-chloronitrobenzene (CNB) have been studied over Pt/CNTs and PtM/CNTs catalysts (M = Mn, Fe, Co, Ni and Cu) in ethanol at 303 K and normal pressure. The results exhibit that the hydrogenation of p-CNB can be carried out over PtM/CNTs catalysts. Both catalytic activities and yields of p-chloroaniline (CAN) are improved. PtFe/CNTs catalyst exhibits the best catalytic activity (TOF is 0.47 s −1), and PtMn/CNTs catalyst exhibits the highest yield of p-CAN (98.5 mol%). Different reductants have also influence on both catalytic activity and yield of p-CAN. Pt/CNTs(II) catalyst exhibits good catalytic activity and stability on the hydrogenation of p-CNB. PtM/CNTs(II) catalysts exhibit low catalytic activity and high yield of p-CAN.
