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.
电纺含铁和氮的碳纳米纤维旨在催化氧还原反应,而不是使用基于 Pt 的催化剂。通过使用超低氧气流量精细地修饰其表面形态,分别将其起始电位和半波电位提高至相对于可逆氢电极的 0.88 V 和 0.76 V,接近基于 Pt 的催化剂的值。
