| Abstract: | Dually supported bimetallic catalysts,0 80Pd 0 20Pt/PVP]/support,were prepared and used in the hydrogenation of nitrobenzene.Catalysts 0 80Pd 0 20Pt/PVP]/Al 2O 3 was the best one among them.The effects of the loading level of Pd,the amount of sodium acetate and the solvent used on the reaction were investigated.The catalyst0 80Pd 0 20Pt/PVP]/Al 2O 3 exhibited high activity,selectivity and stability in the hydrogenation of nitrobenzene under the favorable reaction conditions. |
