Nitrogen-doped porous carbon is an ideal electrode material for supercapacitors, and the development of efficient and inexpensive graphene-based porous carbon is of great significance to promote its application. In this study, a bottom-up in-situ method is developed to grow nitrogen-doped 3D graphene-like porous carbon (Cu-GL-NPC) with Cu as a catalyst. The Cu-GL-NPC possessed the high nitrogen content of 7.64% and the high ratio of pyrrolic nitrogen, along with open three-dimensional porous structure, which led to the smooth transfer of electr...
