结果表明，通过氢还原后形成具有载体的纳米颗粒，合理地改变金属-载体的相互作用，可以微调Pd的催化性能;在α-CHOHCHOH-邻位二醇单元的氢解中，发现在C-O键上断裂C-C键的能力随着d-带填充的减少而显著增加，而改性后Pd的d带中心的上移增强了其断裂C-O键的能力。
It is shown that the catalytic properties of Pd can be fine-tuned by rationally varying the metal–support interaction through the formation of bimetallic nanoparticles with a support after hydrogen reduction; in the hydrogenolysis of a –CHOHCHOH– vicinal diol unit, the ability to break the C–C bond over the C–O bond is found to increase significantly with the decrease in d-band filling, while the ability to break the C–O bond is enhanced by the upshift of the d-band center of modified Pd.
