Recently, the incorporation of foreign atoms (e.g. nitrogen, phosphorus, fluorine, and oxygen, etc.) into the carbocycle has been demonstrated to be very promising for enhancing the electrochemical property of carbon-based supercapacitor. Herein, for the first time, fluorine and oxygen co-doped porous carbons (FOPCs) were successfully prepared by employing third-class red dates as precursor, which showed high specific surface area (1229 m2 g−1), highly-developed micropores (~ 93%), rich oxygen-content (22.8 wt%) and moderate fluorine doping (1...
