Formic-Acid-Induced using Recyclable-Ionic Liquids as Catalysts for Lignin Conversion into Aromatic Co-Products

Lignin valorization toward value-added chemicals and fuels via electrocatalysis: A perspective

“…Researchers have also improved lignin solubility by directly using an organic solvent [69]. Furthermore, ionic liquid and deep eutectic solvents are also utilized as electrolytes because of their high lignin solubility as well as a board electrochemical window and low volatili- ty [68,[70][71][72][73]. Although both ionic liquids and deep eutectic solvents enhance the electrocatalytic efficiency for lignin depolymerization, their scalable application is still very difficult owing to high cost and laborious recovery [64].…”
