Confined coordination to construct lignin‐based Fe single atoms and CoFe clusters for accelerated oxygen reduction
To advance zinc‐air batteries (ZABs), it is crucial to engineer cost‐effective, highly efficient, and durable transition metal‐based catalysts for the oxygen reduction reaction (ORR). In this study, a lignin‐based coordination framework is established through solvent‐induced assembly. Leveraging the confinement eff...
