Composite fiber as a multifunctional catalyst support for the upgradation of lignin-based chemicals

“…[1][2][3] Lignin, with its abundant benzene rings, exhibits vast potential to generate aromatic platform chemicals, paving the way for their broader application in pharmaceuticals, polymers, biofuels, and other industries. [4][5][6][7] Vanillyl alcohol (VAL), a typical lignin derivative with significant potential and value in fine chemical synthesis, food, and biomedical fields, 8,9 can be synthesized through the oxidative degradation of lignin to vanillin (VAN), followed by its hydrogenation. However, the hydrogenation of VAN is a complicated process, involving the hydrogenation of the aldehyde group in VAN, hydrodeoxygenation of the alcoholic hydroxyl group in VAL to 2-methoxy-4-methylphenol (MMP), and deep hydrogenation of the benzene ring.…”
