Effect of surfactants on electrochemical properties of vanadium-pentoxide nanoparticles synthesized via hydrothermal method

Vanadium pentoxide (V₂O₅) nanoparticles were synthesized via an anionic, cationic and non-ionic surfactant assisted hydrothermalmethod in which Ammonium metavanadate (NH₄VO₃) was used as precursor. The synthesized nanoparticles were characterized by using powder X-Ray Diffractometer, Scanning Electron Microscopy and UV-Vis spectroscopy. Crystalline nanoparticles were formed using different surfactants like Sodium Dodecyl Sulphate (SDS), Cetyltrimethylammonium Bromide (CTAB), Polyvenylpyrollidone (PVP) and Sodium Dodecyl Benzene Sulfonate (SDBS). The specific capacitance of V₂O₅ was calculated in 0.5 M KCl and 0.5 M Na₂SO₄ aqueous electrolyte by using cyclic voltammetry (CV). Electrochemical impedance, and Chronocoulommetry studies revealed a good capacitive and charge-discharge behavior of the prepared V₂O₅, which is very promising for the application for next-generation high-performance electro-chemical supercapacitors.
