Polyindole (PIn), cobalt, and acetylene black (C) were used to obtain non-precious-metal nanocomposite electrocatalysts for the oxygen reduction reaction (ORR). We studied the composition, structure, and electrochemical properties of these materials. The PIn-Co/C-pyr obtained with treatment at elevated temperature, have much greater electrocatalytic activity in ORR in 0.05 M sulfuric acid in comparison with nonpyrolyzed (metal-polymer composite) PIn-Co/C, which may be attributed to differences in the catalytically-active sites in these composites.
