Waste wine mash-derived doped carbon materials as an efficient electrocatalyst for oxygen reduction reaction
Oxygen reduction reaction (ORR) is a core reaction of fuel cell and metal-air cell. In recent years, it has been a hot topic to study non-precious metal catalysts for ORR. Herein, we have used waste wine mash-derived carbon, melamine and ferric chloride to prepare a Fe and N- co-doped carbon catalyst. The specific surface area of the catalyst is up to 1066.6 m(2) g(-1). And its wave potential is 15 mV higher than that of commercial Pt/C catalyst. The ORR on our catalyst followed a four-electron pathway; and it has high stability and high impressive immunity to methanol. After continuous oxygen reduction of 30,000s, the retention rate is 90%.
