E lectrospinning with a simple and controllable process has extremely received considerable concerns by virtue of the fabrication and development of nanofibers. Moreover, nanofibers are playing an increasing impact on energy conversion and storage devices, especially for fuel cells based on oxygen reduction reaction(ORR), in view of the rich porosity, large surface area, excellent mass transportation and simply tunable composition, as well as good mechanical strength. In this review, we mainly introduce the primary principle of electrospinning technique, electrochemical reaction mechanism of ORR and synthetic strategies, and summarize the recent advances of unique non-noble-metal nanofibers on the basis of metal-organic framework(MOF) derivatives, single-atom catalysts(SACs) and transition metal oxides. More importantly, we emphasize on the influences of the components, morphology and architecture of advanced electrospun catalysts on their corresponding electrochemical performances towards ORR. Finally, the remaining puzzles and perspectives for further development of the electrospinning nanofibers involving electrocatalysis are presented. It is envisioned that this review would offer an important direction in designing novel electrocatalysts based on electrospinning nanofibrous structures and developing their potential.
