Deeba, Rana; Chardon-Noblat, Sylvie; Costentin, Cyrille published an article in 2021. The article was titled 《Molecular Catalysis of Electrochemical Reactions: Competition between Reduction of the Substrate and Deactivation of the Catalyst by a Cosubstrate Application to N2O Reduction》, and you may find the article in ChemElectroChem.Computed Properties of C6H4N2 The information in the text is summarized as follows:
In the context of mol. catalysis of electrochem. reactions, the competition between reduction of the substrate and deactivation of the catalyst by a cosubstrate is investigated. It is a frequent situation because proton donors are ubiquitous cosubstrates in reductive electrochem. reactions and mol. catalysts, either transition metal complexes or organic aromatic mols., and are often prone to electrohydrogenation. We provide a formal kinetic anal. in the framework of cyclic voltammetry, and we show that the response is governed by two parameters and that the competition does not depend on the scan rate. From this anal. a methodol. is proposed to analyze such systems and then illustrated via the study of N2O to N2 electroreduction catalyzed by 4-cyanopyridine in acetonitrile electrolyte with water as proton donor. Incidentally, new insights into the mechanism of 4-cyanopyridine radical anion protonation are revealed. The experimental part of the paper was very detailed, including the reaction process of 4-Cyanopyridine(cas: 100-48-1Computed Properties of C6H4N2)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Computed Properties of C6H4N2
