In this paper, the tungsten oxide (WO3) nanofiberhas been fabricated via a hydrothermal by taking H2WO4 as precursors. The H2WO4 precursors are prepared by reaction between aqueous Na2WO4 and HCl solution. The tungsten oxide (WO3) nanofiberhas been doped with reduced graphene oxide (rGO). The as prepared samples are characterized by UV/Vis spectroscopy, FTIR spectroscopy, and X-ray diffraction. In optical properties, the band gap of WO3 nanofiberand rGO/ WO3 nanocomposite has been calculated. |
