Effects of TiO2 structure and Co addition as a second metal on Ru-based catalysts supported on TiO2 for selective hydrogenation of furfural to FA

Abstract The TiO2 supported Ru-based catalysts were prepared with 1.5 wt% Ru and 0–0.8 wt% Co on various TiO2 (anatase, rutile, P-25, and sol–gel TiO2) and studied in the liquid-phase selective hydrogenation of furfural to furfuryl alcohol (FA) under mild conditions (50 °C and 2 MPa H2). The presenc...
