Supermolecule polymerization derived porous nitrogen-doped reduced graphene oxide as a high-performance electrode material for supercapacitors

High-doping-leveled (10.5 at.%) porous nitrogen-doped reduced graphene oxide (P-NrGO) is synthesized through supermolecule polymerization and hydrothermal process. The introduced melamine cyanurate (MC) not only used as a spacer but also as a pore forming agent, well as a nitrogen source to induce in-situ N doping.214
