| Abstract: | Hydrogenation properties of chloronitrobenzene with Pt/CNT and PtM/CNT catalysts (M = La, Ce, Pr, Nd and Sm) have been studied in ethanol at 303 K and normal pressure. The results show that the hydrogenation of chloronitrobenzene can be carried out with PtM/CNT catalysts. The conversion of chloronitrobenzene is above 99% and chloroaniline is the main product in hydrogenation with PtM/CNT catalysts. Electron deficient species of the second element promote the specific rate constant turnover frequency expressed as per surface Pt atom by activating the nitrogen-oxygen bond. PtCe/CNT catalyst exhibits the best catalytic activity (TOF = 0.47 s-1) and the highest yield of p-CAN (97.5 mol%). PtSm/CNT catalyst shows the best yields for m-CAN (98.0 mol%) and o-CAN (96.9 mol%). PtCe/CNT (1.0 wt%) catalyst exhibits good stability for hydrogenation of p chloronitrobenzene |
