A series of Cu/TiO₂-SiO₂ catalysts were prepared by a sol-gel hydrothermal method and characterized by BET, SEM, TEM, XRD, XPS, and H₂-TPR. The catalysts were used for selective hydrogenation of furfural to furfuryl alcohol. Results show that based on the Cu/SiO₂ catalyst, introducing a part of TiO₂ into the carrier while keeping very large specific surface area would promote the reduction of CuO, inhibit the growth of Cu crystal particles, and improve the dispersity of Cu particles in the catalyst. The electronegativity of Cu is enhanced in the double-loaded Cu/TiO₂-SiO₂ catalyst, compared with single-loaded Cu/SiO₂ or Cu/TiO₂ catalysts. The Cu/TiO₂-SiO₂ catalyst containing 0.40 g/g (40 wt%) TiO₂ in the carrier shows high furfural hydrogenation performance.
