Pt-free ORR catalyst: Fe-modified N-doped carbon nanofibers (Fe-N-CNFs) are a promising non-Pt catalyst for the oxygen reduction reaction (ORR). A pulverization approach to effectively excavate a larger number of active sites embedded in the Fe-N-CNFs for the ORR is possible. Facile ball milling results in a significant enhancement in the Fe-based ORR active sites and the corresponding ORR activity of the Fe-N-CNFs.
