| Popis: | A series of Pt/Nb 2 O 5 catalysts were synthesized at different temperature conditions to investigate metal-support interaction effect on the catalytic activities in the aqueous phase hydrodeoxygenation of 1,6-hexanediol at 523 K and 5.5 MPa. The increase of calcination temperature of Nb 2 O 5 support over 773 K lowered surface area as well as acidity of Nb 2 O 5 , which altered the electron density of the active center Pt as characterized by XANES analysis. It was demonstrated that the bifunctional catalytic nature of Pt/Nb 2 O 5 catalyst having high acidity and electron deficiency could promote the dehydration of 1,6-hexanediol followed by hydrogenation with high selectivity toward n -hexane. |
