Abstract: The Pd/Ni bimetallic catalyst was prepared by replacement reactions, characterized byX-raydiffraction, CO chemisorption, and H2 temperature-programmed desorption, and evaluated for the hydrogenation of cyclohexene, styrene, and acetone. The results show that Pd atoms are monolayer-dispersed on the Ni surface in this Pd/Ni catalyst. Consequently, the Pd/Ni catalyst is much more active than Pd/Ni and Pd/γ-Al2O3 with the same Pd loading prepared by the conventional impregnation method.
