Study of physisorbed HQ on activated charcoal material as a supercapacitor. (A) Cyclic voltammograms at scan rates of 5 (green trace), 10 (blue), 20 (red), and 50 (black) mV/s. (B) Proposed overall mechanism of HQ redox chemistry on electrode surface when HQ is physisorbed on AC. (C) Total capacitance, double layer capacitance, and pseudocapacitances calculated from cyclic voltammograms at 5 mV/s scan rate for HQ-AC in different pH electrolyte solutions.
