Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Searching for non‐precious electrocatalysts with high performance to replace the expensive Pt‐based electrocatalysts for oxygen reduction reaction (ORR) is a key issue in the industrial‐scale application of fuel cells. In this study, we have reported the synthesis of an iron doped N‐containing carbon materials, derived from duck blood, a wasted material in the duck meat production, as a novel and cost‐effective catalyst in ORR. The as‐prepared electrocatalysts were characterized by means of powder X‐ray diffraction, scanning electron microscopy, Raman spectroscopy and X‐ray photoelectron spectrometer. In 0.1 mol L⁻¹ KOH solution, the ORR onset potential and the half‐wave potential for the iron doped N‐containing carbon materials are 33 mV and –120 mV respectively, which are close to those of commercial Pt/C (20 wt%). In addition, the iron doped N‐containing carbon materials exhibit excellent tolerance to methanol crossover, which makes it a promising electrocatalyst for ORR in fuel cell.</p> </abstract>
