Electrospinning has received tremendous attention in terms of the design and fabrication of 1D nanofibers for oxygen electrocatalysis in fuel cells and metal‐air batteries, owing to their high surface area, short charge transport path, superior chemical stability, etc. In this review, a brief introduction is given for fuel cells, metal‐air batteries, and the operation principle of electrospinning. After that, the recent progress of the noble‐metal‐free electrocatalysts prepared through electrospinning, mainly containing heteroatoms‐doped electrospun carbon nanofibers (ECNFs), ECNFs functionalized with transition metal nanoparticles and their compounds (alloy, oxides, carbides, nitrides, sulfides, phosphides), and unique nanostructured transition metal‐nitrogen‐ECNFs (including single‐atom catalysts) are summarized. In this section, electrospun electrodes with self‐standing peculiarity are emphasized. Next, other kinds of electrospun nanofibers based on oxides, nitrides, and carbides as electrocatalysts or their hybrid materials are also discussed. Finally, the prospects and possible future research direction of electrospun NFs‐based oxygen electrocatalysts are also presented. This comprehensive review is anticipated to be valuable and helpful in the context of understanding the design and fabrication of advanced energy conversion and storage devices.

用于氧气电催化的电纺无机纳米纤维：设计，制备和进展

由于静电纺丝的表面积大，电荷传输路径短，化学稳定性强等优点，因此在燃料电池和金属空气电池中用于氧电催化的一维纳米纤维的设计和制造方面，静电纺丝受到了极大的关注。简要介绍了燃料电池，金属空气电池以及静电纺丝的工作原理。之后，通过静电纺丝制备的无贵金属电催化剂的最新进展，主要包括杂原子掺杂的电纺碳纳米纤维（ECNF），用过渡金属纳米颗粒及其化合物（合金，氧化物，碳化物，氮化物，硫化物，包括磷化物）和独特的纳米结构过渡金属-氮-ECNF（包括单原子催化剂）。在这个部分，强调具有自立性的电纺丝电极。接下来，还将讨论基于氧化物，氮化物和碳化物作为电催化剂或它们的杂化材料的其他种类的电纺纳米纤维。最后，还介绍了静电纺丝基于NFs的氧电催化剂的前景和可能的未来研究方向。在理解先进的能量转换和存储设备的设计和制造的背景下，预期这项全面的回顾将是有价值的和有益的。还介绍了静电纺基于NFs的氧电催化剂的前景和未来的研究方向。在理解先进的能量转换和存储设备的设计和制造的背景下，预期这项全面的回顾将是有价值的和有益的。还介绍了静电纺基于NFs的氧电催化剂的前景和未来的研究方向。在理解先进的能量转换和存储设备的设计和制造的背景下，预期这项全面的回顾将是有价值的和有益的。
