| 摘 要： | 利用金属置换反应制备了表面单层分散型Pt/Ni双金属催化剂,并测定了该催化剂对环己烯、苯乙烯、丙酮和丁醛气相加氢反应的催化性能. 结果发现,这种催化剂具有比传统浸渍法制备的相同Pt含量的Pt/Ni和Pt/Al2O3催化剂更高的催化活性.

| Abstract: | The monolayer dispersed Pt/Ni bimetallic catalyst was prepared through a simple replacement reaction,and its catalytic activity for the hydrogenation of cyclohexene,styrene,acetone,and butyl aldehyde was tested.The Pt/Ni catalyst prepared by the replacement reaction showed much higher activity than Pt/Ni and Pt/Al_2O_3 catalysts with the same Pt loading prepared by the conventional impregnation method. |

| Keywords: | platinum nickel monolayer-dispersed bimetallic catalyst hydrogenation replacement reaction |
