Herein, a self-supported carbon community is designed by means of the only pyrolysis of Carica papaya seeds (biomass) with none activation agent and demonstrates their discipline emission and supercapacitor functions. The pyrolysis of seeds within the argon ambiance results in the formation of interconnected, rod-like constructions. Moreover, the hydrofluoric acid remedy not solely eliminated the impurities but in addition resulted within the formation of CaF2 nanocrystals with the addition of F-doping. From the sector emission research, the turn-on discipline values outlined at an emission present density of ~ 10 µA/cm2 have been discovered to be ~2.16 and 1.21 V/µm for as-prepared carbon and F-doped carbon, respectively. Notably, F-doped carbon displays a excessive emission present density of ~9.49 mA/cm2 and has been drawn at an electrical discipline of ~2.29 V/µm. The supercapacitor research have been carried out to exhibit the multi-functionality of the ready supplies. The F-doped carbon electrode materials displays the very best particular capacitance of 234 F g−1 at 0.5 A g−1. To exhibit the precise supercapacitor software, the HFC // HFC symmetric coin cell supercapacitor system was assembled. The general multifunctional applicability of the fabricated hybrid constructions gives a futuristic strategy to discipline emission and power storage functions.
