摘要 | 5-Hydroxymethylfurfural (HMF) which is derived from cellulosic biomass is an important platform for value added downstream chemicals and fuels via diversified processes. Nanoceria rods, cubes and octahedra were synthesized by a hydrothermal method and used as supports for preparing Au/CeO2 catalysts via deposition-precipitation. The morphology effect of CeO2 in the Au/CeO2 catalysts was investigated in selective oxidation of HMF to 2,5-furandicarboxylic acid (FDCA). The Au/CeO2-rod was more efficient for the oxidation of HMF and the TOF value of Au/CeO2-rod was 6.3 (min(-1)), which was 7 times as high as that of Au/CeO2-cube (0.9 min(-1)) and 32 times as high as that of Au/CeO2-oct (0.2 min(-1)). The experimental results and catalyst characterization implied that the oxygen vacancies on the Au-CeO2 interface determined the catalytic activity by affecting the size, and valence of Au and the interfacial acidic properties. The Au/CeO2-rod with the highest oxygen vacancies presented the higher proportion of cationic gold and more interfacial Lewis acidic sites between ceria and Au nanoparticles. Moreover, a synergistic effect between the interfacial Lewis acid, homogeneous base and neighboring Au particles promoted the oxidation reaction via efficiently activating the hydroxyl, aldehyde and molecular O-2. |
