Willow lignin oxidation and depolymerization under low cost ionic liquid

Willow biomass was subjected to different pretreatmentconditions with triethylammonium hydrogen sulfate as solvent, andthe produced lignin solutions were treated by oxidation either homo-geneously using H2O2as oxidant or by heterogeneous catalysis usingTiO2. Lignin, residual lignin, oil, and the rec...
