Key Points

This research aims to develop bimetallic catalysts to enhance the performance of rechargeable zinc-air batteries.
A bioinspired bimetallic single-atom catalyst (Fe/Ni-NC) is synthesized on N-doped porous carbon from ZIF-8.
The introduction of Fe and Ni atoms into the carbon support is sequenced for optimal performance.
Electrochemical tests are conducted to assess the catalytic activity and stability of the catalyst.
The Fe/Ni-NC catalyst shows a significant increase in activity for both oxygen evolution and reduction reactions.
Improvement in battery performance is evidenced by higher discharge capacity compared to traditional catalysts.
Stability tests indicate the catalyst maintains efficacy over extended cycles, enhancing longevity of zinc-air batteries.

Implication

Demonstrates enhanced performance of bimetallic electrocatalysts in rechargeable zinc-air batteries, suggesting improved battery efficiency.

Abstract

A bioinspired bimetallic single-atom-based catalyst (Fe/Ni-NC) is generated on N-doped porous carbon derived from ZIF-8 for rechargeable zinc-air batteries (ZABs). Fe and Ni atoms are sequentially introduced into the support...
