摘要：

In a macrocyclic structure, the contribution of the metal-N-4 sites to oxygen reduction reaction (ORR) remains controversial.ln this study, to investigate the contribution of macrocyclic cathode catalysts to the ORR properties in the macrocyclic sites excluding various synthetic conditions, the macrocyclic cathode catalysts were prepared using an electrochemical polymerization method at room temperature. The ORR activity of the deposited electrodes as catalysts was evaluated in an alkaline medium. To clarify the core metal as an active site in the macrocyclic structure as a cathode catalyst for the ORR, a CN--poisoning test of core metal site was performed.
