New strategy to prepare N-doped holey graphene for high-volumetric supercapacitors


N-doped holey graphene (N-HG) was successfully prepared by a novel “Bottom-up” strategy with scalable and low cost characteristics. The as-obtained N-HG possessed amounts of in-plane holes, a high specific surface area (1602 m2 g-1), a high nitrogen content(9.92 at. %) and could easily stacked to form high density carbon monolith which presented a maximum volumetric capacitance of 397 F cm-3 for supercapacitors. This work defines a novel but effective “Bottom-up” pathway to prepare N-HG and its derived high density carbon own high volumetric capacitances  for supercapacitors.
