“…The parameters of EPR spectra of PhenDNO +• radical cation and unprotonated phenazine-di-N-oxide radical anion agree well with literature data [23]. We have investigated the effect of additions of water (as base) [3] and acids (HClO 4 and CF 3 COOH) [14] on the shape of CV and intensity of EPR signal of cation-radical PhenDNO + . It was found that the addition of water up to 0.4 M does not affect the shape of CV of PhenDNO [3].…”

“…Taking into account the results of quantum-chemical modeling and data in [15][16][17], we believed [14] that the oxidation of PhenDNO at nanopaper electrode is probably accompanied by a similar effect. The observed increase in the PhenDNO oxidation current relative to the current of the oxidation of the ferrocene reference could be explained by adsorption of PhenDNO, which leads to a splitting of nanotube bundles and an increase in the area of nanopaper electrode accessible for the electrolyte.…”

“…1a) for the preparation of nanopaper were synthesized in our Institute by the electric arc method using the Ni/Y catalyst. It was found [14] that the oxidation current of PhenDNO at SWCNT electrode in the absence of cyclohexanol exceeded by 13 times the oxidation current of ferrocene reference. To clarify the mechanism of this effect, we performed in [14] a quantum-chemical modeling of adsorption of PhenDNO and ferrocene at SWCNT electrode.…”

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.
