## Description

- description: Developing bifunctional electrocatalysts with superior oxygen evolution
    and reduction reaction (OER/ORR) activity and high durability is crucial for rechargeable
    metal-air batteries. Transition-metal-based layered double hydroxides (LDHs) are
    promising in the application as cost-effective and high-performance air cathodes.
    Herein, hierarchical composites of ZIF-derived CoNiFe LDH nanocages in-situ grown
    on Ag nanowires (CoNiFe LDH@Ag NWs) are synthesized as carbon-free bifunctional
    oxygen electrocatalysts. The hollow structure of LDH and heterointerface with
    conductive Ag substrate not only maximizes exposure of active sites, but also
    ensures effective electron transfer. In addition, the hybridization with Ag induces
    structural disorder and unsaturated coordination in the LDH shells, thereby enhancing
    intrinsic catalytic activity. Theoretical calculations reveal that incorporation
    of Ag species could tune the electronic states and reduce the reaction barriers
    of OER and ORR. As a result, CoNiFe LDH@Ag NWs exhibit a bifunctional overpotential
    of 0.63 V. Applied as a carbon-free cathode in zinc-air battery, CoNiFe LDH@Ag
    NWs yields a high specific capacity of 808 mAh g−1 and long cycling stability
    up to 300 h. This work provides new insight into the design of LDH hierarchical
    structure for efficient and durable electrocatalysts.
