Phosphorus and nitrogen co-doped reduced graphene oxide as superior electrode nanomaterials for supercapacitors

Phosphorus/nitrogen co-doped reduced graphene oxide (PN-rGO) materials have been prepared by one-step pyrolysis of the functionalized GO (FGO) with hexachlorocyclotriphosphazene and p -phenylenediamine for supercapacitor devices fabrication.
