Herein, Ru/SBA-15 catalysts were prepared <i>via</i> impregnation, and used for the production of cyclohexanols from lignin-derived phenols. The catalyst samples were characterized by XRD, XPS, TEM, <i>etc.</i>, where the Ru⁰ species was speculated as the active phase. 5 wt% Ru/SBA-15 with small Ru particle size (4.99 nm) and high Ru dispersion (27.05%) exhibited an excellent hydrogenation activity. A high cyclohexanol yield of >99.9% was achieved at 20 °C for 5 h in an aqueous phase, and the catalyst indicated stable activity and selectivity after five runs. Crucially, Ru/SBA-15 exhibited a zero-order reaction rate with an apparent activation energy (Ea) as low as 10.88 kJ mol<sup>-1<RSC advances9352-9362https://www.ebi.ac.uk/biostudies/studies/S-EPMC8985087biostudies-literatureLow temperature catalytic hydrodeoxygenation of lignin-derived phenols to cyclohexanols over the Ru/SBA-15 catalyst.PMC8985087Liu XLi GHu CSu ZFeng SfalseLow temperature catalytic hydrodeoxygenation of lignin-derived phenols to cyclohexanols over the Ru/SBA-15 catalyst.Cyclohexanol and its derivatives are widely used as chemical intermediates and fuel additives.
