Callerya Atropurpurea shells derived nitrogen doped carbon quantum dots of electrodes for symmetrical and asymmetrical supercapacitors

Abstract Callerya Atropurpurea shells were utilized as activated carbon precursors in a one-stage activation process at 700 °C using H2SO4, NaOH and KOH as activating agents. Herein, carbon quantum dots (CQDs) were produced via self-doping using urea as a nitrogen source. The structural, functional,...
