Nonylphenol polybenzoxazines-derived nitrogen-rich porous carbon (NRPC)-supported g-C3N4/Fe3O4 nanocomposite for efficient high-performance supercapacitor application

In this study, nitrogen-rich porous carbon (NRPC)/g-C 3 N 4 /Fe 3 O 4 composite was produced and tested for supercapacitor application in a 1 M KOH electrolyte. The resultant composite has a high specific capacitance (385 F g −1 at 1 A g −1 ).
