An Efficient Oxygen Evolution Catalyst for Hybrid Lithium Air Batteries: Almond Stick Type Composite of Perovskite and Cobalt Oxide

An Efficient Oxygen Evolution Catalyst for Hybrid Lithium Air Batteries: Almond Stick Type Composite of Perovskite and Cobalt Oxide

We investigated the electrochemical composite effect between cobalt oxide and Nd0.5Sr0.5CoO3-δ (Co-NSC). A double phase Co-NSC composite was successfully synthesized by a new synthesis process rather than a single phase Nd0.5Sr0.5Co1.1O3-δ perovskite. The composite has good catalytic activity, high...

Zusammenfassung:We investigated the electrochemical composite effect between cobalt oxide and Nd0.5Sr0.5CoO3-δ (Co-NSC). A double phase Co-NSC composite was successfully synthesized by a new synthesis process rather than a single phase Nd0.5Sr0.5Co1.1O3-δ perovskite. The composite has good catalytic activity, high number of transferred electrons (3.9) compatible with Pt/C, and low concentration of the peroxide species (HO−2) yields (
