Abstract

Hydrodeoxygenation of the lignin monomer guaiacol was performed on the bifunctional catalysts of noble-metals supported on acidic matrices. The catalytic roles of metal nanoparticles and acidic supports were elucidated using the acid-site-measurement-dependent catalysis results, which demonstrated that metals were responsible for the hydrogenation of aromatic rings while metal-deposited acidic supports were indispensable to the deoxygenation of oxygenates. Among various combinations of metals and supports, Rh/SiO2-Al2O3 and Ru/SiO2-Al2O3 exhibited the highest cyclohexane yields.
