“…In the case of labeling with 3 , no voltammetry could be observed in the region of system I, confirming that the voltammetry observed above for the case of labeling with 1 was due to substitution of surface quinone groups by both amine groups. However, additional voltammetric waves concurrent with those of system III could be observed corresponding to substitution of single carbonyl groups by one of the amine groups in 3 to form quinimine-like adducts which have redox potentials similar to quinones themselves. − For both 4 and 5 the corresponding nitro group reduction could be observed, indicating again that formation of the nitro derivative of a quinone-imine adduct was formed on the surface, but again no voltammetry corresponding to system I could be observed.…”

Differentiating between ortho- and para-Quinone Surface Groups on Graphite, Glassy Carbon, and Carbon Nanotubes Using Organic and Inorganic Voltammetric and X-ray Photoelectron Spectroscopy Labels

ortho-Quinones can be differentiated from other oxygen-containing surface functional groups on the surfaces of graphite, glassy carbon, “bamboo-like”, and “hollow-tube” multiwalled carbon nanotubes and single-walled carbon nanotubes by chemically labeling them with either an inorganic hexamminechromium(III) complex or organic 1,2-phenylenediamine derivatives. Both types of labels can be observed using cyclic voltammetry or by X-ray photoelectron spectroscopy and used to quantify the numbers and relative distribution of ortho-quinones from other oxygen-containing species on the surface including electroactive para-quinones which are not labeled. Labeling of ortho-quinones with 1,2-phenylenediamine derivatives results in the formation of phenazine-like adducts on the graphitic surface which have a distinct voltammetry particularly from that of the underivatized para-quinones.

“…They proposed that the oxidation mechanism of three PDs depends on the PD monomer structure and solution pH value . The electrochemical characteristics including capacities and electrode efficiencies of PDs and their derivatives such as methyl- p PD, chloro- p PD, 2,6-dichloro- p PD, 4-hydroxy- m PD, amino- p PD, and 12DAN in basic electrolyte (1.44 M NaOH solution) were systematically studied for the first time by Glicksman in 1961 . In 1963, Mark and Anson first reported the effect of acid strength on the electrooxidation of PDs and their N -substituted derivatives including N,N -dimethyl- p PD and N -phenyl- p PD on Pt electrode by chronopotentiometry .…”

“…Previous studies on the electrochemical oxidation of 1,2-diaminobenzene have yielded only partial informa-tion on the reaction mechanism (1,2,(7)(8)(9)(10)(11)(12)(13)(14). It was shown that the reaction products were pH dependent, with electrode filming occurring at lower and middle pH, but not at high pH (1,2).…”

A rapid scanning spectrometer and classical electrochemical techniques have been combined in a spectroelectrochemical experiment using optically transparent electrodes to study electrode filming on the oxidation of 1,2‐diaminobenzene; alone and in the presence of Ni (II). Spectroelectrochemical studies of short‐lived redox intermediates and mechanisms of the oxidation at platinum electrodes are determined. Cyclic voltammetry showed the oxidation of 1,2‐diaminobenzene to be irreversible, and on successive scans without cleaning the electrode the peak current dropped significantly with each scan until ultimately no current flowed. This situation is indicative of an insulating film completely coating the electrode. This behavior was observed both with and without Ni(II) being present in solution. However, there were significant differences in the rate and nature of the filming. Spectroelectrochemically, it was observed that the nature of the film on 1,2‐diaminobenzene oxidation was independent of time and potential. A conducting film is initially formed, and on top of this a nonconducting film forms which eventually insulates the electrode. With Ni(II) present, the oxidation mechanism is potential dependent. At lower potentials a product containing nickel is formed which does not coat the electrode. At higher potentials the product was found to be the same insulating film which coated the electrode in the oxidation of 1,2‐diaminobenzene without the presence of Ni(II).
