摘 要：<正>Hydrogenations for olefinic double bondscatalyted by the Pd-Fe2O3/D3520 resin and Pd-Bi2O3/D3520 resinwere reported.These catatysts were characterized by IR spectraand 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 electronsfrom Pd, leading to the lowering of the hydrogenation rate.When Pd/Bi atom ratio=1, the hydrogenation was inhibitedentirely. The IR spectra of resin D3520 showed no significantchanges when Pd and the metallic oxides were supported on thepolymerparticles. That indicates that there are no obvious inter-actions between Pd （or metallic oxides） and supporter. Finally,a possible hydrogenation mechanism was also supposed.
