Abstract:<\/h4>\n
Durable and highly active oxygen electrocatalysts are crucial to the large-scale application of rechargeable zinc-air batteries. Here we utilize the N4<\/sub> unit in phthalocyanine molecule to trap the tungsten atoms scratched off from the tungsten carbide milling balls and place the obtained W-N4<\/sub> unit adjacent to the Fe-N4<\/sub> units from iron (\u2161) phthalocyanine, resulting in highly active Fe-N4<\/sub>\/W-N4<\/sub> diatomic sites with well-pronounced 3d-5d hybrid for efficient and durable oxygen electrocatalysis. The electron distribution of the Fe-N4<\/sub> site is optimized by the neighboring W-N4<\/sub> site, which facilitates the O2<\/sub> activation and the desorption of *OH and enhances the catalytic activity of the Fe-N4<\/sub> site. Meanwhile, the unsaturated 5 d orbitals and tunable valence of the W atoms could modulate the electronic state of the Fe species, prevent leaching, and further enhance the catalytic stability. The resulting zinc-air battery with Fe,W-N-C air cathode exhibits notable cycling stability and repeatability for over 10,000 h. This enhanced stability highlights the possibility of developing 5 d metal-boosted 3 d metal active sites for the fabrication of efficient oxygen electrocatalysts and stable zinc-air batteries.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41467-025-63540-w Authors: Yifan Li, Hanlin Wang, Chang Chen, Xuesong Xie, Yang Yang, Xuehai Tan, Keren Jiang, Ning Chen, Hao Zhang, Zhi Li Abstract: Durable and highly active oxygen electrocatalysts are crucial to the large-scale application of rechargeable zinc-air batteries.
