The flexible molecular approach used to assemble the individual catalyst components (SiO₂ , ionic liquid, nanoparticles) led to outstanding catalytic properties. In particular, intimate contact between the nanoparticles and the phosphonium ionic liquid is required for the deoxygenation reactivity. The Rh@SILP(Ph₃ -P-NTf₂ ) catalyst was active for the hydrodeoxygenation of benzylic ketones under mild conditions, and the product distribution for non-benzylic ketones was controlled with high selectivity between the hydrogenated (alcohol) and hydrodeoxygenated (alkane) products by adjusting the reaction temperature. The versatile Rh@SILP(Ph₃ -P-NTf₂ ) catalyst opens the way to the production of a wide range of high-value cyclohexane derivatives by the hydrogenation and/or hydrodeoxygenation of Friedel-Crafts acylation products and lignin-derived aromatic ketones.1e:T4aa,Selective hydrotreatment of β-O-4 ether bonds in lignin is a key strategy for the lignin valorization. The current catalytic strategy can only transfer β-O-4 model compounds to aromatics. Also, further upgrading was still needed to convert those aromatics/phenols into aviation fuels or chemicals (e.g., cycloalkanes, cycloalcohols) in a following step. Herein, a one-pot method for the hydrotreatment of lignin β-O-4 ether to cycloalkanes/cycloalcohols over NiLa/CNT was reported due to the introduction of La. The dehydroxylation of 2-phenoxy-1-phenylethan-1-ol to phenethoxybenzene was the key step during the hydrotreatment, followed by the β-O-4 bond cleavage to ethylbenzene and phenol, which was then simultaneously hydrogenated to afford ethyl cyclohexane and cyclohexanol. The catalyst acidity was found to be important during the hydrotreatment process, especially the Brønsted acid sites. This was confirmed by control experiments using different reaction intermediates as reactants, as well as analysis of products distribution and DFT calculations. This work provides a novel and economical method for the selective hydrotreatment of lignin model compounds into aviation fuel.
