Abstract

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.

Keywords: carbon nanofibers; electrospinning; iron-based catalysts; oxygen etching; oxygen reduction reaction.
