“…Thus, the catalytic current of the oxidation of pyrazine-di-N-oxides in the presence of cyclohexane [5,6] increased threefold at the addition of 1 M Н 2 O. In contrast, when trifluoroacetic acid was added, the catalytic currents decreased and the CVs shifted toward higher anodic potentials.…”

“…Previously [3,5,6], we obtained data on the diverse effects of water (as a base) and acid additions on the catalytic currents of oxidation of aromatic di-N-oxides in the presence of a number of substrates. Thus, the catalytic current of the oxidation of pyrazine-di-N-oxides in the presence of cyclohexane [5,6] increased threefold at the addition of 1 M Н 2 O.…”

“…The detection of the same intermediate in CH 3 OH and CH 3 OD indicated that CH 3 group of alcohol was involved in formation of the intermediate. To explain the results obtained in [1][2][3][4][5][6][7][8], the E 1 C 1 E 2 C 2 mechanism of two-stage electrode process characterized by catalytic current at the second electrode stage was suggested. The overall two-electron catalytic oxidation of the organic substance in complex with aromatic di-Noxide radical cation was assumed to occur.…”

“…Previously, it was found [1][2][3][4][5][6][7][8] that electrochemically generated aromatic di-N-oxide radical cations are carriers of active oxygen that is capable of activating the C-H bond of the substrate. The mechanism of the oxidation of phenazine-di-N-oxide (PhenDNO), pyrazine-di-N-oxide, and its substituted derivatives in the presence of organic compounds (alcohols, ethers, cyclohexane) was studied by cyclic voltammetry [1][2][3][4][5][6][7][8].…”

In the study of the oxidation of PhenDNO in methanol and its deuterated derivatives CH 3 OD and CD 3 OD by EPR electrolysis [3], EPR spectra of radical intermediates were recorded with g-factor of 2.0023 in CH 3 OH and CH 3 OD and 2.0023 and 2.0036 in CD 3 OD.…”

Catalytic oxidation of methanol (MeOH) in the absence of noble metals and noble metal oxides as catalysts, and the use of metal‐free materials are inexpensive and attractive process for practical use in electrocatalysis, sensors, and in direct methanol fuel cells. In previous works, it was found that the use of single‐walled (SWCNT) or multi‐walled (MWCNT) carbon nanotube paper electrodes instead of GC increases the catalytic efficiency of organic compounds oxidation in the presence of aromatic di‐N‐oxides by several times. In this work, the effect of non‐covalent interactions on the catalytic efficiency of MeOH oxidation in the presence of 2,5‐di‐Me‐pyrazine‐di‐N‐oxide (Pyr1) in 0.1 M Bu4NClO4 solution in acetonitrile at SWCNT and MWСNT paper electrodes was studied by the methods of quantum chemical modeling, Raman spectroscopy, and using electrochemical data. New factors determined the features of mechanism of MeOH oxidation on CNT electrodes and lead to an increase in the catalytic efficiency of the electrode process in comparison with the GC electrode were established.
