摘 要：<正> A series of polymer - supported Pd -Fe2O3 composite catalysts were prepared and their hydrogenation property was investigated. It was found that the above catalysts have good catalytic hydrogenation activity for carbon - carbon double bonds systems and reusability. Furthermore, XPS and IR spectra showed that active component in the composite catalysts is atomic Pd（0）. An addition of a small amount of Fe2O3 has a promotive action upon hydrogenation activity of the catalysts, which indicated that there are some strong interactions （electron transfer） between Pd（0） and Fe（Ⅲ） species. Based on these results, a possible catalytic hydrogenation mechanism was also suggested.
