a Comparisons of phenolic monomer yields, delignification degrees and C5/C6 retentions over different catalysts. b GC spectra of the lignin-derived monomers. c 2D HSQC NMR spectra of lignin-derived products from RCF of birch over RuN/ZnO/C (DMSO-d6). d Three-dimensional version of the HSQC end-chain region. e GPC spectra of lignin-derived products. Reaction conditions: birch wood (250 mg), catalyst (25 mg, 10 wt%), MeOH (15 mL), 240 °C, H2 (3 MPa at 25 °C, 12 MPa at 240 °C), and 4 h. TON denotes turnover numbers, calculated based on the total number of moles of Ru in the catalyst (molphenols molRu−1).
