The 15%wt Ni/TiO2 catalysts were prepared by incipient impregnation method. The result showed that Ni supported on anatase-rutile mixed phase TiO2 (91% Rut and 9% Ant, A2) provided the highest furfuryl alcohol yield at 43.8% due to the relatively strong Ni-TiO2 interaction, its appropriate crystallite sizes, and high average pore sizes. Furthermore, the effect of cobalt as a promoter on Ni/ TiO2-A2 catalysts was studied. The result showed that the Ni-Co/TiO2-A2 catalysts exhibited poorer catalyst performances compared to the monometallic Ni/TiO2, probably because addition of cobalt can lower the reduction temperatures of Ni/TiO2 and weaken the metal-support interaction.
