Green Solvent Pretreatment of Biomass: Insights into Lignin Structural Evolution in Organosolv and Deep Eutectic Solvent Systems.
Lignocellulosic biomass is a key renewable resource for producing biofuels, biomaterials, and high-value chemicals, but its efficient utilization is hindered by the recalcitrant lignin-carbohydrate complex (LCC) network. Organosolv (OS) and deep eutectic solvent (DES) pretreatments have emerged as promising green strat...
