CATALYTIC ELECTROREDUCTION OF MOLECULAR OXYGEN USING MANGANESE

Article abstract of DOI:10.1246/cl.1985.1917

The water-soluble manganese porphyrin in the title was found to catalyze electroreduction of oxygen.The reaction could be explained by an electrochemical (EC) catalytic regeneration mechanism, and at the porphyrin concentrations of more than ca. 5E-5 mol dm^-3 two-electron reduction was attained.Electronic absorption and magnetic circular dichroism (MCD) spectroscopies have suggested that the active species of the porphyrin is in a high-spin divalent state.
