A facile one-step low temperature hydrothermal method was adopted to the synthesis of graphene-decorated V2O5 nanobelts (GVNBs). The decoration of graphene enhanced the conductivity of GVNBs. From the electron energy loss spectroscopy analysis, reduced graphene oxide (rGO) sheets are inserted into the layered crystal structure of V2O5 which further enhanced the conductivity of V2O5 nanobelts. The as synthesized material was applied to the electrochemical energy storage applications. The vanadium rich composition of GVNBs showed high specific capacitance. The long term cyclic stability and the capacitance retention of 82% even after 5000 cycles revealed that GVNBs could be a promising candidate for supercapacitor applications. |
