| 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/c-Al2O3 with the same Pd loading prepared by the conventional impregnation method.
