Palladium-nickel bimetallic catalysts supported on poly-(4,7-diazaheptyl)siloxane were prepared. XFS analysis indicated that the complexation occurred between nitrogen atom of the polymer and Pd⁰, PdCl₂ or NiCl₂. The hydrogenation activity of the catalyst for decene-1, cyclohexene, propenoic acid, styrene and nitrobenzene has been investigated. The result indicated that the bimetallic catalyst showed higher activity in the hydrogenation of styrene and nitrobenzene. The activity of the bimetaliic catalyst was affected by the Pd/Ni atom ratio and temperature.
