摘要:

以廉价天然植物果实红枣作为唯一碳源, 采用牺牲模板法制备了一种具有层状多孔结构的铁氮共掺杂碳材料(Fe-N-CM). 采用X射线粉末衍射、 X射线光电子能谱、 透射电子显微镜、 氮气吸-脱附仪和拉曼光谱对Fe-N-CM样品的形貌和结构进行了表征, 用旋转圆盘电极及环盘电极对Fe-N-CM催化剂的氧还原反应(ORR) 性能进行了研究. 结果表明, 所制备的层状多孔Fe-N-CM材料比表面积达到429.8 m2/g, 铁颗粒在材料表面均匀分散, 铁和氮的协同作用使Fe-N-CM具有良好的氧还原催化活性, 其对氧还原反应的催化稳定性和抗甲醇性能优于商业Pt/C催化剂.

Abstract:

A layered porous Fe-N-codoped carbon material(Fe-N-CM) was synthesized by sacrificial template method using cheap natural product red date as exclusive carbon source, g-C3N4 as sacrificial template and nitrogen source. The morphology and structure of Fe-N-CM were characterized by XRD, XPS, TEM and BET. The oxygen reduction reaction(ORR) performance of the obtained catalyst was evaluated by rotating disk electrode(RDE). The results show that Fe particles well dispersed are Fe-N-CM with high surface area(429.8 m2/g) and synergistic effect of Fe and N exhibits high ORR activity. And the long-term stability and methanol resistance of Fe-N-CM for ORR are even superior to commercial Pt/C.

Key words: Sacrificial template method, Fe and N codoped carbon, Electrocatalysis, Oxygen reduction reaction
