摘　　要：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 Cu_(1)Co_(1)/N-C was originated from the synergistic interactions of Cu and Co species,where Co^(0)and Cu^(0)simultaneously adsorb and activate H_(2),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 Cu_(1)Co_(1)/N-C adsorbed FAL with a tilted η^(1)-(O)configuration.The superior Cu_(1)Co_(1)/N-C showed excellent adsorbed ability towards H_(2) and FAL,but weak adsorption for FOL.Therefore,Cu_(1)Co_(1)/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.
