The direct cleavage of C−O bonds in lignin and its derivatives via hydrogenolysis is an essential reaction process for conversion. Herein, we design a MgAl2O4 supported Ru catalyst using facile green method involving ball milling microwave heating. optimal catalyst, 0.5Ru/MgAl2O4, displayed enhanced catalytic performance 4−O−5 linkage scission compared to 0.5Ru/Al2O3 0.5Ru/MgO, achieving tuenover frequency 352.9 h−1 diphenyl ether (DPE) 0.5Ru/MgAl2O4 with low loading achieved complete conversion DPE, 43.8% yield cyclohexane (CHE) 42.6% cyclohexanol (CHL) after 2 h at 160 °C 1.5 MPa H2. promising activity can be attributed the abundant electron-rich Ru0 species high dispersion formed on MgAl2O4, derived from strong electron transfer support Ru. mechanism bond, followed by phenyl ring hydrogenation, was confirmed rigorous experiments. This work provides inspiring idea developing efficient heterogeneous catalysts utilization resources hydrogenolysis.

Lignin-based guaiacol and its derivatives can be hydrogenated to synthesize 2-methoxycyclohexanols (2-MCHs), widely used in the pharmaceutical industry, while efficient catalytic conversion of guaiacols into 2-MCHs is challenging due interference side reaction CAr-OCH3 bond cleavage. In this work, highly selective hydrogenation various guaiacyl lignin-derived phenols (yields 86%-97%) was realized over a single-atom Ru-based catalyst (Ru1/o -CeO2-ov) that preferentially exposes CeO2(111) plane has abundant oxygen vacancies. Control experiments mechanism studies expounded Ru-O-Ce active site for aromatic ring guaiacols, exposed (111) vacancies ceria reduce activation energy hydrogenation, thereby enabling generate corresponding products with high selectivity. Response surface optimization indicated temperature time have relatively more significant effects on 2-MCH yield. Moreover, Ru1/o -CeO2-ov exhibited excellent reusability, extensively applicable hydrogenative dearomatization different types phenols, providing unique solution upgrading biomass feedstock specific structural chemicals.
