(618e) Selective Hydrodeoxygenation of Furfuryl Alcohol on Doped Metal Oxide Catalysts
An alternative design approach is to incorporate transition metal dopants into moderately reducible metal oxides (MO). In the present work, we prepared a series of doped MO catalysts for the selective HDO of furfuryl alcohol, a biomass model compound. Kinetic studies reveal that small amounts of dopant significantly enhance the HDO rate over moderately reducible metal oxide, whereas the same dopant on irreducible silica shows very low activity. By adjusting the dopant-metal oxide ratio, we successfully prevent undesired ring hydrogenation. Finally, catalytic performance combined with scanning transmission electron microscopy (STEM) and X-ray absorption spectroscopy (XAS) reveals the nature of catalytic active sites.
