通过静电纺丝技术和后煅烧法成功制备了一种Fe₃C纳米颗粒嵌入的N掺杂多孔碳纳米管材料(Fe₃C-NCNT)。利用SEM、TEM、XRD、Raman、XPS等对催化剂进行表征,同时对所制备的Fe₃C-NCNT纳米管在电催化氧还原反应时表现出的电催化活性和循环稳定性进行测试。结果表明,Fe₃C@NCNT表现出优异的电催化ORR性能,为制备高效非贵金属电催化剂提供了一种简便有效的通用方法。

Fe₃C-NCNT,a kind of N-doped porous carbon nanotubes embedded with Fe₃C nanoparticles,is successfully prepared through the electrospinning technology combining with a facile post calcination process.The as-synthesized Fe₃C-NCNT is characterized by means of SEM,TEM,XRD,Raman spectroscopy,XPS and other methods,and its electrocatalytic activity and cycling stability for oxygen reduction reaction are determined simultaneously.It is shown that Fe₃C-NCNT exhibits an excellent electrocatalytic ability for oxygen reduction reaction,thus providing a simple and effective general method for the preparation of high-efficiency non-noble metal electrocatalysts.
