논문 초록 (Abstract)
A composite electrode (CE) consisting of activated carbon and quinine derivative 2-((2-(1H-indol-3-yl) ethyl) amino) naphthalene-1, 4-dione (HBU-551) was probed in different hydrogen ion conducting electrolyte s such as sulfuric acid (H2SO4), hydrochloric acid (HCl), Phosphoric ac id (H3PO4) and ammonium chloride (NH4Cl). The electrochemical performanc es of the CE in the electrolytes were investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and charge-discharge. The different hydrogen ion conductin g electrolytes with different ionic conductivity induce different ele ctrochemical properties in the CE. The specific capacitance is in t he order of H2SO4 > H3PO4 > HCL > NH4Cl at 100 mV/s and a potential rang e of -0.2 - 0.8 (V vs Ag/AgCl).
