Abstract: 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.
