Abstract: Bimetallic CuCo catalysts with different Cu to Co ratios on N-doped porous carbon materials (N-C) were achieved using impregnation method and applied in the hydrogenation of furfural (FAL) to furfuryl alcohol (FOL). The high hydrogenation activity of FAL over Cu1Co1/N-C was originated from the synergistic interactions of Cu and Co species, where Co0 and Cu0 simultaneously adsorb and activate H2, and Cu+ served as Lewis acid sites to activate C=O. Meanwhile, electrons transfer from Cu to Co promoted the formation of Cu+. In situ Fourier transform infrared spectroscopy analysis indicated that Cu1Co1/N-C adsorbed FAL with a tilted η1-(O) configuration. The superior Cu1Co1/N-C showed excellent adsorbed ability towards H2 and FAL, but weak adsorption for FOL. Therefore, Cu1Co1/N-C possessed 93.1% FAL conversion and 99.0% FOL selectivity after 5 h reaction, which also exhibited satisfactory reusability in FAL hydrogenation for five cycles.
