Added-Value Chemicals from Lignin Oxidation
Molecules, 2021 Lignin is the second most abundant component, next to cellulose, in lignocellulosic biomass. Large amounts of this polymer are produced annually in the pulp and paper industries as a coproduct from the cooking process—most of it burned as fuel for energy.

Direct conversion of lignin to functionalized diaryl ethers via oxidative cross-coupling
Nature Communications, 2023 Efficient valorization of lignin, a sustainable source of functionalized aromatic products, would reduce dependence on fossil-derived feedstocks. Oxidative depolymerization is frequently applied to lignin to generate phenolic monomers.

Oxidative Depolymerization of Chitosan by Hydroxyl Radical
Bioscience, Biotechnology, and Biochemistry, 1996 Oxidative depolymerization of chitosan induced by oxygen radical-generating systems was studied. Chitosan, but not chitin, was susceptible to oxidative depolymerization by hydroxyl radical generated through Cu(II)–ascorbate and ultraviolet–H2O2 systems in time- and concentration-dependent manners.
