In 2019,Materials Today: Proceedings included an article by Mazur, D.; Pariiska, O.; Kurys, Y.. Synthetic Route of C5H7N3. The article was titled 《Co-N-C electrocatalysts derived from nitrogen containing conjugated polymers for hydrogen evolution》. The information in the text is summarized as follows:
New Co-N-C electrocatalysts for hydrogen evolution reaction (HER) were successfully prepared via heat treatment of a series of nitrogen containing conjugated polymers – N-CP (poly-m-phenylenediamine, poly-8-aminoquinoline, poly-2,6-diaminopyridine, poly-5-aminoindole) with carbon black and Co(NO3)2. For the first time, we demonstrated influence of the N-CP type, like a nitrogen precursor, on activity toward HER of Co-N-C composites in acidic media, which may be related, in particular, to the differences in the mol. structure of polymers. It was found, that the best HER performance inherent to an electrocatalyst obtained based on poly-5-aminoindole (overpotential at 5 mA/cm2 ∼ 177 mV, Tafel slope – 132 mV/dec). According to obtained exptl. data, it was assumed that the hydrogen evolution on Co-N-C catalysts takes place by the Volmer-Heyrovsky mechanism and the Volmer step is rate-limiting. The experimental part of the paper was very detailed, including the reaction process of 2,6-Diaminopyridine(cas: 141-86-6Synthetic Route of C5H7N3)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Synthetic Route of C5H7N3
