Rechargeable zinc-air batteries are widely recognized as a highly promising technology for energy conversion and storage, offering a cost-effective and viable alternative to commercial lithium-ion batteries due to their unique advantages. However, the practical application and commercialization of zinc-air batteries are hindered by the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Recently, extensive research has focused on the potential of first-row transition metals (Mn, Fe, Co, Ni, and Cu) as promising alternatives to noble metals in bifunctional ORR/OER electrocatalysts, leveraging their high-efficiency electrocatalytic activity and excellent durability. This review provides a comprehensive summary of the recent advancements in the mechanisms of ORR/OER, the performance of bifunctional electrocatalysts, and the preparation strategies employed for electrocatalysts based on first-row transition metals in alkaline media for zinc-air batteries. The paper concludes by proposing several challenges and highlighting emerging research trends for the future development of bifunctional electrocatalysts based on first-row transition metals.
可充电锌空气电池作为一种极具前景的能量转换和存储技术，因其独特优势而被广泛认可，是商业锂离子电池经济高效且可行的替代品。然而，锌空气电池的实际应用和商业化受到氧还原反应（ORR）和析氧反应（OER）缓慢动力学的阻碍。最近，大量研究聚焦于第一排过渡金属（锰、铁、钴、镍和铜）作为双功能ORR/OER电催化剂中贵金属的潜在替代物，利用它们的高效电催化活性和出色耐久性。本文综述了碱性介质中用于锌空气电池的基于第一排过渡金属的电催化剂在ORR/OER机理、双功能电催化剂性能及制备策略方面的最新进展。文章最后提出了一些挑战，并强调了基于第一排过渡金属的双功能电催化剂未来发展的新兴研究趋势。
