PROBLEM TO BE SOLVED: To convert dissolved oxygen molecules into water by four-electron reduction and four-proton transfer, and to efficiently extract the free energy as an electrode potential. To provide an excellent oxygen reduction complex catalyst. A μ-oxo binuclear manganese (III) complex and a μ-oxo manganese (III, IV) mixed valence dinuclear complex are a β-diketone ligand, tetraphenylporphyrin, octaethylporphyrin, protoporphyrin I Dinuclear complex comprising a porphyrin-based macrocyclic ligand such as X, 4-pyridylporphyrin, a phthalocyanine-based macrocyclic ligand, an acetylacetonealkylenediimine-based ligand, or a salicylaldehyde alkylenediimine-based ligand The system is an oxygen reduction catalyst. |
