The products of thermodestruction of homo- and heterobinuclear Co(II) and Ni(II) hexamethylenediaminetetraacetates as electrocatalysts for oxygen reduction are studied. As revealed, the maximum activity in oxygen electroreduction is manifested by electrocatalysts containing pyrolysis products of cobalt complex obtained at 600?С. As shown, the activity of electrocatalysts increases due to formation of active centres (nanoinclusions) on the surface of carbon matrix. Electrocatalyst activity depending on the ratio of metals in homo- and heterobinuclear complexes with H4Hmdta decreases in the series: {Со–Со}???{Со–Ni}???{Ni–Ni}.
