“…A special case of EE mechanism, where an overall transfer of three electrons is assumed, i.e. the first oneelectron transfer is followed by the second two-electron transfer step, has been also studied [24]. The latter model is applicable for electrochemical deposition of bismuth and antimony, two important processes for preparation of popular bismuth and antimony film electrodes used in modern anodic stripping voltammetry [43].…”

“…The application of square-wave voltammetry (SWV) [1] for mechanistic and kinetic studies [2][3][4][5][6][7][8] of electrode processes increases permanently in the last decade, due to the intensive development of the theory of the technique for a variety of electrode mechanisms and electrode geometries [9][10][11][12][13][14][15][16][17]. A plethora of intriguing studies has been conducted in relation to the kinetics of charge transfer processes at liquid/liquid interfaces [18][19][20][21][22][23], electrochemistry of immobilized proteins [24,25], and catalytic mechanisms [26][27][28], revealing that SWV is highly suited for both mechanistic and kinetic characterization of electrode reactions, besides its excellent analytical performances [29][30][31][32][33][34] and its appropriateness for bioanalytical applications [35][36][37][38][39][40][41].…”

The kinetics of surface confined electrode reactions of alizarin, vitamin B12, and vitamin K2 is measured with square‐wave voltammetry over a wide pH interval, by applying the recent methodology for kinetic analysis at a constant scan rate [V. Mirceski, D. Guziejewski, K. Lisichkov, Electrochim. Acta 2013, 114, 667–673]. The reliability and the simplicity of the recent methodology is confirmed. The methodology requires analysis of the peak potential separation of the forward and backward component of the response as a function of the pulse height (SW amplitude), for a given frequency (i.e. constant scan rate) of the potential modulation.

“…The theoretical results relevant to the voltammetric behavior of the so-called EE (electrochemical-electrochemical), ECE (electrochemical-chemical-electrochemical), and EECat (electrochemical-electrochemical-catalytic) redox mechanisms under conditions of cyclic staircase voltammetry are comprehensively elaborated in the recent work of Gulaboski et al [55]. Moreover, the voltammetric features of EEcat [56], CE (chemical-electrochemical) [57], ECE [58], and EC [54] redox mechanisms have also been studied under conditions of square-wave voltammetry by Gulaboski et al Mirceski et al [59][60][61], Lovric and Komorsky-Lovric et al [62][63][64][65][66][67][68][69][70][71], and Molina et al [72][73][74][75][76] also made several great contributions towards theoretical understanding of the complex voltammetric behavior of coenzyme Qs under various conditions. Several recent review works report on the major achievements in the theory of square-wave and cyclic voltammetry [77][78][79][80][81].…”

Quinones constitute a big family of organic redox active compounds that are overwhelmingly involved in important physiological processes. The most important members in the class of quinones are, indeed, the plastoquinones and the coenzyme Q (CoQ) derivatives. Voltammetry of coenzyme Q family members attracts significant attention since 50 years ago. In this work, we refer to some of the most important voltammetric features of coenzyme Qs studied in aprotic and in aqueous media. While the redox chemistry of coenzyme Q members in non-aqueous aprotic organic solvents can be described by two consecutive one-electron transfer steps, more complex situation exists in the voltammetry of coenzyme Qs performed in aqueous media. Although it has been claimed for a while that the voltammetric processes of coenzyme Qs in aqueous solutions proceed via formation of semiquinone radical intermediate species, it has been recently proven that this can be not completely true. Intensive voltammetric and spectroscopic studies of coenzyme Q systems in buffered and non-buffered aqueous media revealed that hydrogen bonding between electrochemically created CoQ species and the water molecules plays an important role in stabilizing electrochemically generated species of these systems. We also pay attention to the amazing redox chemistry of coenzyme Qs in strong alkaline media, while we refer to the chemical features of novel coenzyme Q derivatives obtained under such conditions. Hints are presented about the antioxidant capacity of some of the novel hydroxylated coenzyme Q systems. Also, the possibility of these systems to bind and transfer earth-alkaline cations across biomimetic membranes is shortly elaborated. In the end, we refer to some relevant theoretical works that describe closely the voltammetric behavior of various coenzyme Q systems. We believe that this short review will contribute towards better understanding of the amazing chemistry of coenzyme Q derivatives.
