dc.description.abstract | Among the redox active molecules, methyl viologen (MV) is the most promising redox species in an aqueous organic redox flow battery, featuring the stable redox reaction MV2+/MV center dot+. Its electrochemical properties and solubility significantly depend on the counter-anion. Herein, we introduce the nitrate as a counter-anion to methyl viologen dication to obtain a new water-soluble methyl viologen compound (MVdN) and identify the effects of nitrate as counter-anion on electrochemical properties of methyl viologen. Nitrate leads to similar to 3.5 M solubility in water and good electrochemical reversibility (i(p,a)/i(p,c) = 0.79, Delta E = 54 mV) with fast mass transfer (D = 5.13 x 10(-5) cm(2)center dot s(-1)) of methyl viologen, which is superior to commonly used methyl viologen dichloride(MVdCl). Additionally, flow cell performance from 40 to 100 mA cm(-2) exhibited 99% coulombic efficiency and comparable performance with MVdCl. Nitrate could be a promising choice as a counter anion to methyl viologen as aqueous redox active molecule. | - |
