Iron–cobalt bimetal oxide nanorods as efficient and robust water oxidation catalysts

Iron–cobalt bimetal oxide nanorods (Fe_1.1Co_1.9O₄) can efficiently catalyze water oxidation under the reaction conditions of photocatalytic and electrochemical. This superior photocatalytic performance owes to the best balanced flat-band potential of Fe_1.1Co_1.9O₄.
