spectroscopies are highlighted to unravel active-site structures and catalytic pathways. Furthermore, we summarize the impact of COF-based bifunctional catalysts on key ZAB performance indicators such as power density, discharge capacity, round-trip efficiency, and long-term cycling stability. Finally, we outline current challenges, including scalable synthesis, interfacial engineering, and durability and provide future perspectives on integrating machine learning and advanced characterization to accelerate the discovery of next-generation ZAB electrocatalysts. Collectively, this review underscores the pivotal role of bifunctional catalyst design in unlocking the practical potential of high-performance, sustainable, and rechargeable zinc-air batteries.
