Figure 6. (A) TOF comparison of 1a hydrogenation reaction on Ru1/o-CeO2-ov and literature catalysts; (B) Hydrogenation performance of different lignin-derived phenols catalyzed by Ru1/o-CeO2-ov (a 150 °C; b 160 °C, 4 h; c 4 h; d 200 °C, 3 MPa H2, 4 h); 2D HSQC NMR spectra of authentic lignin oil in the aromatic region (C); methoxy region (D), and aliphatic region (E) before and after the reaction. 2D HSQC NMR: Two-dimensional heteronuclear single quantum coherence nuclear magnetic resonance.
