The FeP/Fe-N,P-C nanocomposite are able to show high electrocatalytic activity in oxygen reduction reaction (ORR). It was found that Co-N-C ORR electrocatalysts, which are obtained by pyrolysis of deep eutectic solvent (DES) based on 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and hydrated nitrate Co (II) together with carbon black (Vulcan XC72), are characterized by long-term electrochemical stability in the process of oxygen reduction, which is higher or comparable to that for commercial Pt/C catalyst. It was found that the relationship between Vulcan XC72 and Co-containing DES in the precursors significantly affects the composition and electronic structure of the corresponding Co-N-C composites, determining their electrocatalytic properties in ORR. The possibility of using cobalt-containing DES based on choline chloride for preparation of carbonized Co-N-C catalysts for ORR has been shown. The ability of the best of the developed carbonized Co-N-C electrocatalysts in the manufactured model of the low-temperature fuel cell, as well as in the model of the zinc-air cell has been established.
