Solvent Effects on the Electro-oxidation of Iodide Ion

The electrochemical characteristics of the mixture of 1-ethyl-3-methylimidazolium tetrafluoroborate and 1-ethyl-3-methylimidazolium iodide

“…There is a single oxidation peak for various solvents such as water, methanol and acetic acid [19,20]. In acetonitrile, acetone and acetic anhydride, two well defined oxidation peaks were observed [21,22]. Zhang et al reported the electro-oxidation behavior of I À in 1-butyl-3-methylimidazolium tetrafluoroborate with two diffusion controlled oxidation peaks.…”

Investigation on the electro-oxidation of iodide in the room temperature ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate at platinum electrode

“…In solvents such as water, methanol and acetic acid, iodide yielded a single oxidation peak [18,19]. In others, including acetic anhydride, acetone, acetonitrile and semi-solid ruthenium complex molten salt, two well-defined oxidation peaks are observed [20][21][22][23]. Up to now, nothing concerning the electro-oxidation behavior of iodide in 1- The aim of this study is, firstly, to carry out a more detailed investigation on the electrochemical behavior of iodide in [C 4 mim][BF 4 ] with linear sweep voltammetry (LSV) and cyclic voltammetry (CV); secondly, to propose an electrode reaction mechanism of iodide in accord with the experimental results.…”

Unexpected Complexity in the Electro-Oxidation of Iodide on Gold in the Ionic Liquid 1-Ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide

“…26 On platinum, the overall oxidation process shown in eq 1 may occur in one step, giving rise to a single voltammetric process (as observed in aqueous media 26,28−30 ) or in two steps (via an I 3 − intermediate), giving rise to two voltammetric processes (as observed in acetonitrile 26,28,31 and ionic liquids 17,20−24 ):…”
