Effect of rGO doping on hydrothermally Synthesized WO_3Nanofibers

摘要

In this paper, the tungsten oxide(WO_3)nanofiberhas been fabricated via a hydrothermal by taking H_2WO_4 as precursors. The H_2WO_4 precursors are prepared by reaction between aqueous Na_2WO_4 and HC1 solution. The tungsten oxide (WO_3)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 WO_3nanofiberand rGO/ WO_3 nanocomposite has been calculated.
