Description
Summary:•Hierarchical feather duster-like CNT@WO3 composite is prepared by solvothermal method.•The WO3 nanosheet arrays grow vertically on the CNT surface.•The composite shows high specific capacitance and good cycling stability. In order to develop active material with promising properties for supercapacitor, the feather duster-like CNT@WO3 composite is synthesized by a facial on-step solvothermal method. The as-prepared material shows the superior electrochemical properties with high specific capacitance (496 F g−1 at 0.5 A g−1) and long-lasting cycle stability (96.3% retention after 8000 cycles at 100 mV s−1) in 0.5 mol L−1 H2SO4 electrolyte. This simple preparation method and superior performance can make significant contribution in the synthesis and future application in energy storage material.
