摘要

以聚丙烯腈(PAN)和石墨化氮化碳(g-C3N4)共同作为碳/氮前驱体材料

醋酸亚铁作为铁源

利用静电纺丝技术结合高温热解法制备了系列铁氮共掺杂的碳纤维基复合碳材料(Fe-N-CFC)

研究了PAN和g-C3N4的质量配比对所制得的催化剂样品的形貌结构及其氧还原反应(ORR)催化性能的影响.优化组成的Fe-N-CFC-2材料对ORR的半波电势和极限电流分别为-0.04 V和4.32 mA·cm-2

与商业Pt/C催化剂活性接近

而其抗甲醇性能和ORR催化稳定性明显优于Pt/C

是一种有应用潜力的ORR催化剂.

Abstract

Iron and nitrogen co-doped carbon fiber-based carbon hybrid materials(Fe-N-CFC) were prepared by electrospinning combined pyrolysis method

using polyacrylonitrile(PAN) and graphitic carbon nitride(g-C3N4)as mixed carbon/nitrogen precursors

ferrous acetate as iron source. The effect of mass ratio of PAN to g-C3N4 on the morphology and oxygen reduction reaction(ORR) performance of the obtained Fe-N-CFC materials was investigated. The half-wave potential and limiting current density of the optimized sample Fe-N-CFC-2 for ORR are-0.04 V and 4.32 m A·cm-2

respectively

which can be comparable to commercial Pt/C catalysts. Moreover

the methanol resisitance and the duarability of Fe-N-CFC-2 are superior to Pt/C.
