Hydrothermal synthesis, spectroscopic, optical and electrochemical characterization of vanadium dioxide nanostructures
VO2(B) has been successfully synthesized via one step hydrothermal process using vanadium source as V2O5 and 2-Hydroxypropane-1,2,3-tricarboxylic acid as reducing and structure directing agent at 230°C for 24 hr. The product compound was analysed through X-ray diffraction (XRD) and scanning electron microscopy (SEM), and its physicochemical properties are characterized by FTIR and UV-VIS spectroscopy. The obtained VO2 (B) nanoparticles are under 10nm with optical band gap of 2.67eV. Thin film of VO2 (B) nanoparticles was deposited on ITO substrate was electrochemically characterized by cyclic voltammetry. The electrochemical characterizations have revealed reversible redox behavior which corresponds to the reversible lithium intercalation/deintercalation.VO2(B) has been successfully synthesized via one step hydrothermal process using vanadium source as V2O5 and 2-Hydroxypropane-1,2,3-tricarboxylic acid as reducing and structure directing agent at 230°C for 24 hr.
