Electrochemical behavior of NH4VO3 in glyceline DES studied by cyclic voltammetry method

In the present work, the redox behavior of vanadate ion in deep eutectic solvent (DES) was studied via cyclic voltammetry (CV) method where glyceline DES and NH4VO3 were used as electrolyte and the source of + 5 vanadium ions respectively. The CV showed a quasi-reversible redox couple pattern of + 5...
