Recent Advancements in the Hydrodeoxygenation of Lignin‐Derived Phenols to Cyclohexane‐Based Products Over Supported Ruthenium Catalysts

ChemCatChem, Volume 17, Issue 18, September 19, 2025.
This review elucidates structure‐activity relationships in Ru‐supported catalysts for hydrodeoxygenation of lignin‐derived phenolics to cyclohexane‐based products. It highlights the synergy between Ru nanoparticle size, dispersion, and electronic state with tailored support acidity and defects, enabling efficient hydrogenation–deoxygenation.
