| 英文摘要 | several supported ru catalysts, ru/tio2, ru/zro2, ru/sio2, ru/gamma-al2o3 and ru/sio2-al2o3, were prepared and investigated for propanoic acid aqueous-phase hydrogenation. h-2-tpr, nh3-tpd, pyridine-ftir and propanoic acid-drifts techniques were performed to explore the metal-support interaction, acid sites and key adsorption species. the effect of support on the reaction pathway of c=o hydrogenation and decarbonylation of acyl species was discussed. compared with ru/zro2 and ru/sio2 catalysts, high selectivity of c=o hydrogenation was obtained over the catalysts with more lewis acid sites, such as ru/gamma-al2o3 and ru/sio2-al2o3 catalysts. the drifts results suggest that the formation of adsorption species (acyl, carboxylate and carboxylic acid) is strongly depended on the nature of support. the metal-acid bifunctional sites are indispensable for the c=o hydrogenation of acyl. however, the decarbonylation of acyl on the metal sites requires the relatively weak metal-support interaction and few of lewis acid sites.
