Abstract: Co/Al bimetallic oxide catalyst was prepared and used for catalytic reduction of furfural to furfuryl alcohol. The effects of the active metal ratio on the physical and chemical properties of the catalyst were discussed by adjusting the molar ratio of Co/Al. N₂ adsorption/desorption analysis showed that the series of prepared Co_xAlO_y catalysts were mesoporous materials with an average pore size of about 20 nm. NH₃-TPD analysis showed that the dominance of moderate acid sites was favorable for hydrogenation of furfural to furfuryl alcohol. The prepared Co₃AlO_x with the Co/Al molar ratio of 3∶1 exhibited excellent catalytic activity. Under the operational conditions of 0.3 g furfuryl alcohol, 20 mL solvent 1, 4-dioxane, 0.12 g catalyst Co₃AlO_x, reaction time 3 h, H₂ pressure 2 MPa and reaction temperature 120 ℃, the conversion of furfuryl alcohol was more than 98.95%, and the yield of furfuryl alcohol could reach 96.25%. XRD, TEM and XPS analysis showed that Co₃AlO_x existed in the mixed phase of CoAl₂O₄ and Co₂O₃, and the specific surface area and moderate acid strength were the key factors determining the catalytic activity. The catalytic activity of Co₃AlO_x catalyst could still maintain 83% after 5 cycles, which indicates its good cycle stability.
