Deep eutectic solvents as recyclable solvent-electrolyte systems for electroreductive C-O cleavage of lignin models

Key Points

• The aim is to explore deep eutectic solvents as recyclable systems for cleaving C-O bonds in lignin models.
• Utilized DESs composed of hydrogen bonding donors and acceptors.
• Conducted electroreductive experiments on lignin model ethers.
• Evaluated the recyclability of the solvent-electrolyte systems.
• Demonstrated effective C-O bond cleavage using DESs.
• Recycling of DESs was successful, maintaining their efficacy over multiple cycles.
• Illustrated the potential environmental benefits of using DESs in lignin processing.
