Herein, a self-supported carbon community is designed by the only real pyrolysis of Carica papaya seeds (biomass) with none activation agent and demonstrates their subject emission and supercapacitor functions. The pyrolysis of seeds within the argon environment results in the formation of interconnected, rod-like constructions. Moreover, the hydrofluoric acid therapy not solely eliminated the impurities but additionally resulted within the formation of CaF2 nanocrystals with the addition of F-doping. From the sphere emission research, the turn-on subject 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 subject of ~2.29 V/µm. The supercapacitor research have been carried out to show 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 show the precise supercapacitor software, the HFC // HFC symmetric coin cell supercapacitor system was assembled. The general multifunctional applicability of the fabricated hybrid constructions supplies a futuristic strategy to subject emission and power storage functions.
