| Outline of Final Research Achievements |
We developed the ceria-supported rhenium catalyst modified with palladium (ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25)) for the hydrodeoxygenation of 1,4-anhydroerythritol to tetrahydrofuran with hydrogen as a result of the catalyst optimization. This catalyst was applicable to the reaction of sugar alcohols, and mono-alcoholsand diols are obtained in high yields from substrates
with even and odd numbers of OH groups, respectively. It is verified that the high catalytic performance of the catalyst is due to the tetra/hexavalent redox cycle redox cycle of the isolated Re species on CeO2 surface and the promotion of the reduction of Re species by Pd.
