| Abstract: | Hydrogenations for olefinic double bonds catalyted by the Pd-Fe2O3/D3520 resin and Pd-Bi2O3/D3520 resin were reported. These catatysts were characterized by IR spectra and XPS methods. The XPS investigation indicated that the-electron transfer from Fe atom in Fe2O3 to Pd, enhanced the hy-drogenation activity of the catalysts,and Bi2O3 drew electrons from Pd, leading to the lowering of the hydrogenation rate. When Pd/Bi atom ratio = 1, the hydrogenation was inhibited entirely. The IR spectra of resin 1)3520 showed no significant changes when Pd and the metallic oxides were supported on the polymer particles. That indicates that there are no obvious inter-actions between Pd (or metallic oxides) and supporter. Finally , a possible hydrogenation mechanism ,was also supposed. |
