​Abstract​

 Graphene-decorated single crystalline V₂O₅ nanowires (G–VONs) have been synthesized by mixing graphene oxide (GO) and V₂O₅ suspensions at room temperature. In this process, V₂O₅ nanowires (VONs) are formed spontaneously from commercial V₂O₅ particles with the aid of GO. The as-formed one dimensional G–VONs were characterized by using a X-ray diffractometer, a X-ray photoelectron spectrometer, a scanning electron microscope, and a transmission electron microscope. GO plays a vital role in the VON formation with the simultaneous reduction of GO. A single G–VON showed superior electrical conductivity compared with that of the pure VONs obtained from the sol–gel method. This could be ascribed to the insertion of rGO sheets into the V₂O₅ layered structure, which was further confirmed by electron energy loss spectroscopy.
