Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...
