Protonation reactions of anthraquinone-2,7-disulphonic acid in solution and within monolayers

Anthraquinone-derivatised carbon powder: reagentless voltammetric pH electrodes

“…This reveals a linear response from pH 1 to 9 with a corresponding gradient of ca. 58 mV per pH unit which is consistent with an n -electron, m -proton transfer, where n and m are likely to be equal to 2, consistent with studies of anthraquinone derivatives at mercury electrodes [23,24].…”

Electrochemical behavior and electrocatalytic activity of anthraquinonedisulphonate in solution phase and as doping species at polypyrrole modified glassy carbon electrode

“…Most of the experiments were conducted at room temperature. In acidic medium, quinones can be reduced and produce corresponding hydroquinone and hydroquinone anion through the protonation reaction [6,7,[27][28][29]. As can be seen in this figure, the CVs exhibit a single redox couple with nearly symmetric anodic and cathodic peaks.…”

The Electrochemical Reaction Mechanism and Applications of Quinones

“…For example, different pretreatment or surface modification of carbon electrode brought about a huge difference in kinetics, 9,10 and adsorption of quinones led to unusual electrochemical behavior. 11,12 Such aspects of quinone electrochemistry will be left out of the scope of this review.…”
