In order to facilitate electrochemical oxygen reactions in electrically rechargeable zinc-air batteries (ZABs), there is a need develop innovative approaches for efficient electrocatalysts. Due their reliability, high energy density, material abundance, and ecofriendliness, ZABs hold promise as next-generation storage conversion devices. However, the large-scale application of currently hindered by slow kinetics reduction reaction (ORR) evolution (OER). development heterostructure-based electrocatalysts has potential surpass limitations imposed intrinsic properties single material. This Account begins with an explanation configurations fundamentals electrochemistry air electrode. Then, we summarize recent progress respect variety heterostructures that exploit bifunctional electrocatalytic overview impact on ZAB performance. The range heterointerfacial engineering strategies improving ORR/OER performance includes tailoring surface chemistry, dimensionality catalysts, interfacial charge transfer, mass transport, morphology. We highlight multicomponent design take these features into account create advanced highly active catalysts. Finally, discuss challenges future perspectives this important topic aim enhance activity batteries.

Abstract Platinum group metal (PGM)‐free electrocatalysts have emerged as promising alternatives to replace Pt for the oxygen reduction reaction (ORR) in anion exchange membrane fuel cells (AEMFCs). However, traditional synthesis methods limit single‐atom site density due agglomeration at higher temperatures. This work explores preparation of hierarchically porous atomically dispersed ORR. The materials were prepared via ionothermal synthesis, where magnesium nitrate was used prepare carbon materials. in‐situ formed Mg‐N x sites trans‐metalated yield ORR‐active Fe‐N sites. resulting carbon‐based catalysts displayed excellent electrocatalytic activity, attributed active and high meso‐ macroporosity that enhanced mass transport exposed more accessible
