Highly stable and selective Ru/NiFe2O4 catalysts for transfer hydrogenation of biomass-derived furfural to 2-methylfuran

138Ru/NiFe2O4 catalysts demonstrated effective hydrodeoxygenation for furfural, which is facilitated by the catalytic transfer hydrogenation using 2-propanol as hydrogen source. High 2-methylfuran (MF) yield was obtained over the Ru/NiFe2O4 catalyst under mild reaction conditions, in which the catalyst can be simply recycled using an external magnetic field.
