In this work, a double-layer nitrogen-doped microporous hollow carbon@MoS2/MoO2 nanosphere (NCs@MoS2/MoO2) is prepared via facile method utilizing Mo-mediated in situ growth on polyaniline-coated polystyrene spheres and carbonization process. Because of its unique structure, the as-obtained NCs@MoS2/MoO2 exhibits high specific capacitance (569 F g-1 at 1 A g-1) excellent rate performance (54.8% retention) from to 20 (312 when directly used as supercapacitor electrode. two-electrode system, it 81% retention 91.4% Coulombic efficiency even after 5000 cycles 5 g-1. Therefore, shows be an outstanding material for electrodes.
