Non-platinum oxygen reduction catalysts made from iron cobalt complexes with 1,10-phenanthroline as a precursor supported on multi-wall carbon nanotubes were synthesized by heat treatment with ammonia atmospheres. The mechanism of oxygen reduction in alkaline solution for the catalysts was investigated by X-ray photoelectron spectroscopy and a rotating ring disk electrode method. The correlation coefficients were estimated between effective nitrogen chemical species on the surface of the oxygen reduction catalysts and cathodic current derived from oxygen reduction reaction or 4-electron reduction efficiency. There are no positive correlation between oxygen reduction reaction (ORR) current and the surface concentration of N species. In addition, pyridine-type and pyrrole-type nitrogen species had week negative correlation with ORR current and %H2O. |
