This study builds upon our experience with electrocatalyzed dearomatization of lignin in aqueous systems, which has shown to produce sodium levulinate, 4-hydroxyvalerate, acetate, and formate as major products. Here, we extend this investigation by exploring a water/γ-valerolactone (GVL) solvent system for electrochemical depolymerization lignin, using Na2CO3 electrolyte. GVL, derived from biomass, frequently been employed biomass treatment, notably the Organosolv process. Consequently, various biorefinery strategies have emerged utilizing GVL green platform, primarily its potential delignifying lignocellulosic when combined water dilute acid. proposes step toward concept bioelectrorefinery, aiming convert into aliphatic organic chemicals. Consistent prior work applying current −100 mA over 8 h yielded formate. Confirmation was provided liquid chromatography electrospray ionization high-resolution mass spectrometry, nuclear magnetic resonance, infrared spectroscopy. These findings advance understanding biomass-based highlighting not only treatment but also medium converting valuable
