Innovating Electrosynthesis From Metal Electrodeposition to Organic Chemistry: Deep Eutectic Solvents as Efficient and Sustainable Media

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
This review analyzes deep eutectic solvents (DESs) as efficient media for both organic and inorganic electrosynthesis. The improvements in terms of synthetic opportunities and sustainability are discussed, by exploring the multiple roles of DESs as solvents, electrolytes, and promoters, enabling effective and selective electrosynthesis under mild and ...
