| Outline of Final Research Achievements |
I tried proof of the new oxygen reduction mechanism that was different from the platinum system of heat-treatment barium ion bridging iron porphyrin, which applicants developed as a platinum alternative catalyst for polymer electrolyte fuel cell and evaluated movement stability for a long term under the acidity that was a fault of metalloporphyrin. Iron (III) porphyrin, which became the new high oxidation state to occur because of heat-treatment, adsorbs oxygen molecules with four points of iron and nitrogen in the ring, which faced each other by the dimer structure. As a result, iron (III) caused electric charge separation to iron (IV) and indicated the process such as 4 electron reduction reactions of oxygen happened. On the other hand, a barium ion assists maintenance of the porphyrin dimer structure, and this assistance is important to long-term movement, it was acid resistant and the thing which manifests oxidation resistance was also made clear.
