| Abstract: | Tungsten trioxide nanorods have been generated by the thermal decomposition (450 °C) of tetrabutylammonium decatungstate.
The synthesized tungsten trioxide (WO3) nanorods have been characterized by XRD, Raman, SEM, TEM, HRTEM and cyclic voltammetry. High resolution transmission electron
microscopy and X-ray diffraction analysis showed that the synthesized WO3 nanorods are crystalline in nature with monoclinic structure. The electrochemical experiments showed that they constitute
a better electrocatalytic system for hydrogen evolution reaction in acid medium compared to their bulk counterpart. |
