| Outline of Final Research Achievements |
Iron-nitrogen-carbon (Fe-N-C) supported carbon nanotube (Fe-N-C/CNT) catalyst for the oxygen reduction reaction (ORR) was produced by employing vertically aligned carbon nanotubes (VA-CNT) with high electronic conductivity and iron(II) phthalocyanine (FePc) molecules. Pyrolyzing the composite easily transformed the adsorbed FePc molecules into a large number of iron coordinated nitrogen functionalized nanographene (Fe-N-C) structures, which served as ORR active sites on the individual VA-CNT surfaces. We found that the catalyst exhibited a high ORR activity, which is attributed to the efficient electron transfer between VACNT and Fe-N-C structure, and between VACNTs. We also found that fine control of the thermal history can effectively increase Fe-N-C catalytic site, and consequent ORR activity of the catalyst increase. Our results would provide guidelines for further activation of non-precious ORR electrocatalyst for fuel cells.
