Transition metal catalysts are regarded as one of promising alternatives to replace traditional Pt‐based catalysts for oxygen reduction reaction (ORR). In this work, an efficient ORR catalyst is synthesized by confining Fe3C nanoparticles into N, S co‐doped porous carbon nanosheets (Fe3C/N,S‐CNS) vi...
