摘要：

Hydrogenation of chloronitrobenzene (CNB) over PtM/ZrO2 (M= Cr, Mn, Fe, Co, Ni, Cu) catalysts has been studied in ethanol at 303 K and normal pressure. The results show that the hydrogenation of CNB can be carried out over PtM/ZrO2 catalysts. The order of the hydrogenation rates of CNB is p>m>o, and the yield of chloroaniline (CAN) is p>o>m. PtFe/ZrO2 catalyst shows the highest catalytic activity on the hydrogenation of CNB. PtNi/ZrO2 catalyst shows good yield of CNB to CAN, and 93.3 mol% for o-CAN, 98.0 mol% for m-CAN and 98.5 mol% for p-CAN, respectively.
