Electrochemical trapping of metastable Mn3+ ions for ...

Manganese oxide films are desirable oxygen evolution reaction (OER) catalysts due to their stability in acidic solutions and viability as earth-abundant materials. Enhanced catalytic activity of MnO2 incorporated with Mn3+ provides an imperative for understanding the structural and electronic effects giving rise to the superior OER catalysis. We show that ( i ) Mn3+ is stabilized kinetically ...
