Hydrothermal Synthesis and Electrochemical Performance of WO₃ Nanoparticles

Abstract:

In the present paper, the WO₃ nanoparticles were fabricated via a hydrothermal treatment. The products are characterized in detail by multiform techniques: transmission electron microscopy, X-ray diffraction. The results show that products are WO₃ nanoparticles with diameter of about 100-150 nm. Electrochemistry properties of the prepared WO₃ nanoparticles was characterized by cyclic voltammetry. Cyclic voltammetry results indicate that WO₃ nanoparticles exhibits a remarkable electrochemical activity for hydrogen intercalation. The reason for electrochemical activity of WO₃ nanoparticles is attributed to the formation of H_xWO₃ by hydrogen intercalation/de-intercalation into/out of the tungsten oxide.
