3D N-doped graphene-CNT networks (NGCs) can be obtained by hydrothermal treatment, freeze-drying and subsequent carbonization of graphene oxide-dispersed pristine CNTs in the presence of pyrrole. The resulting NCGs used as a supercapacitor show high specific capacitance, good rate capability and still retain ∼96% of the initial capacitance even after 3000 cycles.
3D N-掺杂石墨烯-CNT 网络（NGC）可通过水热处理、冷冻干燥以及在吡咯存在下对原始 CNT 分散的氧化石墨烯进行碳化得到。所得到的用作超级电容器的 NGC 具有高比电容、良好的倍率性能，甚至在 3000 次循环后仍保留初始电容的约 96%。
