The electrochemical behavior of hydroquinone was examined experimentally using cyclic voltammetry, convolution transform, and deconvolution transform at clean ordinary and nanostructured mesoporous platinum electrodes in 1 mol/l HClO4. The cyclic voltammogram of hydroquinone (HQ) at an ordinary Pt electrode displays an anodic peak at 0.610 V and a cathodic peak at 0.117 V, with a scan rate of 50 mV·s–1. Excellent linearity was recorded between the anodic or cathodic peak currents of hydroquinone and the square root of the scan rate (υ1/2). The anodic and cathodic peak potential separation (∆Ep) was found to be 463 ± 3 mV vs. the saturated calomel electrode (SCE). It was noted that the value of peak potential separation increased with increasing the scan rate. The type of electrode reaction at both platinum electrodes in 1 mol/l HClO4 was examined and discussed. The electrochemical parameters and the nature of the mechanistic pathway of the investigated HQ were determined experimentally and ascertained via a numerical simulation method.

“…To improve the cycling stability of hydroquinone derivatives, various hydroquinone derivatives were synthesized and explored. Zare et al [157] studied the electrochemical behavior of two fluorinated hydroquinone derivatives, 3-fluorocatechol (3FQH 2 , 14−4) and tetrafluoro-p-hydroquinone (TFQH 2 , 14−5), as positive active materials in ARFBs. The standard potential of 3FQH 2 is higher than that of TFQH 2 , but the efficiency of this RFB is lower than that of TFQH 2 .…”

Organic electroactive materials take advantage of potentially sustainable production and structural tunability compared to present commercial inorganic materials. Unfortunately, traditional redox flow batteries based on toxic redox‐active metal ions have certain deficiencies in resource utilization and environmental protection. In comparison, organic electroactive materials in aqueous redox flow batteries (ARFBs) have received extensive attention in recent years for low‐cost and sustainable energy storage systems due to their inherent safety. This review aims to provide the recent progress in organic electroactive materials for ARFBs. The main reaction types of organic electroactive materials are classified in ARFBs to provide an overview of how to regulate their solubility, potential, stability, and viscosity. Then, the organic anolyte and catholyte in ARFBs are summarized according to the types of quinones, viologens, nitroxide radicals, hydroquinones, etc, and how to increase the solubility by designing various functional groups is emphasized. The research advances are presented next in the characterization of organic electroactive materials for ARFBs. Future efforts are finally suggested to focus on building neutral ARFBs, designing advanced electroactive materials through molecular engineering, and resolving problems of commercial applications.
