Functionalized porous carbon with appropriate pore size distribution and open hole texture prepared by H2O2 and EDTA-2Na treatment of loofa sponge and its excellent performance for supercapacitors

Functionalized porous carbon with an appropriate pore size distribution and open hole texture was prepared via the H₂O₂ and EDTA-2Na treatment of loofa sponge followed by carbonization and KOH-activation. The product was employed as a supercapacitor electrode.
