 New carbonized Co-N,В-C nanocomposite electrocatalysts of the oxygen reduction reaction (ORR) based on polyaniline (PAni) doped with boronic acid (PAni-B) and poly-3-aminophenylboronic acid (PAPBA) as well as Co-N-C electrocatalysts (with high surface area) based on poly-o-aminobenzoic acid and nanostructured PAni are obtained and characterizated. It is shown, that usage of multilayered graphene (MLG), instead of carbon black (CB) during obtaining of Co9S8/Co-N-C electrocatalyst derived from poly-2,6-diaminopyridine (PDAP) leads to enhancement of its ORR activity in 0,5 М H2SO4, the reason may be different nature of the dominant active sites (Co9S8, CoNx, C/Nx) in composition of such catalysts. High tolerance of PDAP and MLG derived Co9S8/Co-N-C electrocatalysts to carbon dioxide and methanol, which are capable of poisoning traditional platinum-containing catalysts under conditions of operation of hydrogen and methanol fuel cells, has been established.
