meso-Substituted cobalt and Interface Science, Tokyo University of Science (Kagurazaka, Shinjuku-ku, Tokyo 162-8610, Japan) phyrin and various carbon materials. These electrocatalysts gave rise to electroreduction of O₂ at a remarkably positive potential (E_p= 0.44 V versus saturated calomel electrode (SCE) and showed a high selectivity for the four-electron reduction (n=3.9). The catalyst heat-treated at 600°C showed higher potential (E_p=0.44 V vs. SCE). Electrochemical study and X-ray photo spectroscopy (XPS) analysis revealed that the adsorbed amount of cobalt-porphyrin molecules caused highly effective catalysts for electroreduction of O₂.
