摘要：The bimetallic Pd-Fe catalysts supported on activated carbon were synthesized through the replacement reaction between PdCl2 and Fe colloid which was obtained from Fe(CO)5 by sonication. The influence of PVP on the preparation of the supported catalysts was investigated. A series of characterizations including XRD, H2-TPR, TEM and EDX were used to investigate the composition and structure of Pd-Fe catalysts. The liquid phase hydrogenation of phenylacetylene was used as a probe reaction to study the influence of Fe content on the catalytic properties of the bimetallic Pd-Fe catalysts. The results indicated that, Fe could improve the catalytic activity and selectivity for hydrogenation of the Pd-Fe bimetallic catalyst under the condition with appropriate proportion of Pd and Fe, while more Fe content would reduce its catalytic activity.
