| Abstract | RuO2/MnO2 NRs as an electrode for supercapacitors show a high electrochemical performance with a specific capacitance of 793 F g−1 (based on MnO2) by cyclic voltammetry (CV) at a scan rate of 2 mV s−1 in 1 M Na2SO4 aqueous solution. A good rate capability with a specific capacitance of 556 F g−1 at a current density of 1 A g−1 and a good cycling stability (20% degradation after 1000 cycles) were also achieved. The enhancement of capacitive behavior can be attributed to the conductive RuO2 template with a series resistance of 0.75 Ω and a charge transfer resistance of 0.75 Ω. The results show that an active material such as a MnO2 hybrid with highly conductive 1D nanowires may greatly improve the electrochemical performance for supercapacitors. |
