英文摘要	Silicon carbide (SiC) was extracted using CCl4 and NH3 at 800 degrees C to form a SiC core with a derived nitrogen-doped carbon shell (SiC@N-C), which is explored as a supporting material for iron nanoparticles encapsulated in nitrogen-doped carbon (Fe@N-C) due to its excellent corrosion resistance. The carbon shell around SiC is essential to successfully grow Fe@N-C around SiC@N-C during pyrolysis of cyanamide and iron acetate. In sharp contrast, Fe3Si supported on SiC was obtained using pristine SiC as the supporting material. Fe@N-C/SiC@N-C showed much higher activity for oxygen reduction reaction than SiC@N-C and Fe3Si/SiC, even exceeding that of a commercial Pt/C catalyst in alkaline medium. Furthermore, Fe@N-C/SiC@N-C also demonstrated higher durability and methanol resistance than the Pt/C catalyst.
