One-pot synthesis of shell/core structural N-doped carbide-derived carbon/SiC particles as electrocatalysts for oxygen reduction reaction

An N-doped carbide-derived carbon shell was in situ derived from the surface of SiC nanoparticle by a one-pot method. Characterizations and electrochemistry experiments demonstrate that the prepared particles have a shell/core structure and exhibit a four-electron transfer pathway for oxygen reduction reaction as well as a superior stability compared with Pt/C catalysts.
