One-step synthesis of nitrogen−fluorine dual-doped porous carbon for supercapacitors

The development of doped porous carbon materials has attracted much attention in the application of supercapacitors. This study reports a straightforward one-step method to prepare nitrogen−fluorine dual-doped porous carbon through direct carbonization of commercially available 2-methylimidazole and tetrafluoroterephthalonitrile in the presence of KOH. The obtained porous carbon demonstrated superb specific surface area of more than 2,000 m2 …
