Abstract

Pd/Ni bimetallic catalysts were prepared by replacement reactions,characterized by X-ray diffraction,CO chemisorption and H2 temperature-programmed desorption,and evaluated for hydrogenation of cyclohexene,styrene and acetone.The results show that Pd atoms are monolayer-dispersed on the Ni surface in these Pd/Ni catalysts.Consequently,Pd/Ni catalysts are much more active than Pd/Ni and Pd/γ-Al2O3 with the same Pd loading prepared by the conventional impregnation method.
