GRAPHENE OXIDE-MODIFIED V2O5 NANOPARTICLES: SYNTHESIS, CHARACTERIZATION AND MORPHOLOGICAL PROPERTIES

Abstract

In the present investigation, reduced graphene oxide/Vanadium oxide (rGO/V2O5) nanocomposite was synthesized by the chemical synthesis method. Reduced Graphene oxide was synthesized by Hummer’s method. rGO/V2O5 nanocomposite was also successfully synthesized using ammonium metavanadate as the source of vanadium. The crystalline structure, optical properties, and morphology of rGO/V2O5 nanocomposite were characterized by UV-VIS spectroscopy, IR spectroscopy, X-ray diffraction (XRD) studies, Photoluminescence (PL) spectroscopy and Field Emission Scanning Electron Microscope (FESEM) with EDAX spectroscopy. The optical property was analyzed using UV-Vis and Photoluminescence (PL) spectroscopy. The XRD spectrum showed diffraction peaks corresponding to the crystal planes of crystalline vanadium oxide. The XRD data confirms that V2O5 has an orthorhombic structure. The morphological studies of the nanocomposite revealed crystal-like morphology. The energy dispersive analysis confirmed the presence of Carbon, vanadium and oxygen in the doped rGO/V2O5 lattice. The PL results revealed the emission peak at 617nm and 397nm for V2O5 and rGO/V2O5 nanocomposite, respectively.
