文摘
A novel approach for the synthesis of unique porous NS-GNR by thermal annealing method has been established. The highly synergistic NS-GNR is proposed here for the first time as an electrode for supercapacitors. NS-GNR exhibited an excellent specific capacitance of 442 F g−1 at 0.5 A g−1 and extraordinary rate capability. The assembled NS-GNR//NS-GNR device showed high energy density of ∼23.85 Wh kg−1 at a power density of ∼448 W kg−1.
