Electrospun carbon nanofibers containing iron and nitrogen are designed to catalyze the oxygen reduction reaction instead of Pt‐based catalysts. Their surface morphology is modified finely by using ultralow oxygen flow, and their onset and half‐wave potentials are improved to 0.88 V and 0.76 V versus the reversible hydrogen electrode, respectively, approaching those of Pt‐based catalysts.
