In this paper, we demonstrate a synthesis of mesoporous carbon spheres via self-assembly resorcinol-formaldehyde polymer and surfactant F127 in aqueous phase the presence phytic acid as catalyst phosphorus source. The obtained have high content excellent electrochemical performance. enhancement performance material is primarily attributed to structural characteristics chemical properties atoms being similar those nitrogen atoms, atomic radius slightly larger than that with strong electron donating ability. After successful doping, rich active sites are formed. These examined electrode materials for supercapacitors. characterization revealed possessed an average pore diameter 2.4 nm specific surface area 1207 m2 g- 1. Electrochemical measurements demonstrated capacitance 257.5 F 1 at 0.5 A three-electrode configuration. used supercapacitor electrodes 92.8 current density Furthermore, energy 4.64 Wh Kg- power 150 W retention rate 98.99% 5000 cycles 2 1, extremely highly promising material.
