Phosphorus/nitrogen co-doped and bimetallic MOF-derived cathode for all-solid-state rechargeable zinc-air batteries.

ABSTRACT: With the merits of high safety and energy density, all-solid-state zinc-air batteries possess potential applications in flexible and wearable electronic devices. Especially, the air cathodes with bifunctional catalytic activity, i.e. oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) have been received enormous attention. In this work, we provide a novel phosphorus/nitrogen co-doped and bimetallic metal-organic framework (MOF)-derived cathode configurated with phosphorus-doped bimetallic FeNi alloys and a nitrogen-doped porous carbon layer loaded on graphene (P-FeNi/NC@G). The P-FeNi/NC@G electrode exhibits a superior OER activity with an overpotential of 310 mV at 10 mA cm^-2 and an ORR performance with a half-wave potential of 0.81 V. With P-FeNi/NC@G as
