Herein, RuMn/Al2O3-SiO2 multifunctional catalyst was prepared and efficiently converted lignin-derived phenols into cyclohexanol by aqueous partial hydrodeoxygenation (HDO). The optimal RuMn/Al2O3-SiO2 (Ru/Mn = 2) catalyst achieved 96.8% of cyclohexanol yield with 100% guaiacol conversion under mild reaction conditions (180 °C and 2.0 MPa H2) for 4 h, with a turnover frequency (TOF) of 861.1 h−1, which is better than most results reported. The high performance of RuMn/Al2O3-SiO2 was attributed to the synergic effect of highly dispersed Ru nanoparticles with small size (1.25 nm), the microsphere structure, the appropriate acid sites from Al2O3-SiO2 and acid-base sites from MnOx. |
