A facile procedure for preparing copper and nitrogen co-doped active carbon (Cu-N/OAC) by one-step complexed was reported and applied in liquid-phase hydrogenation of furfural (FAL). The facile procedure resulted in high Cu nanoparticles dispersion on OAC with Cu0 and Cu+ sites and apparently promoted the catalytic activities during furfural hydrogenation reaction. The obtained Cu-N/OAC-800 shows 99.5% FAL conversion with 98.4% selectivity to furfuryl alcohols (FOL) under reaction condition of 150 °C, 2 MPa and 6 h. These results indicated that the excellent catalytic performance of the catalyst was due to the synergic effects of nitrogen doping and Cu metal active sites.
