Lignin-Based Carbon Nanofibers as Electrodes for Vanadium Redox Couple Electrochemistry

open access: yesNanomaterials, 2019
Three different types of lignin (kraft, organosolv and phosphoric acid lignin) were characterized and tested as precursors of electrospun nanofibers. Polyethylene oxide (PEO) was added as a plasticizer and dimethyl formamide (DMF) employed as a solvent ...
