摘要：

We herein report the preparation of an Fe-N-doped carbon nanoparticle- carbon nanofiber (Fe-N-CNP-CNF) composite using a solution plasma process followed by heat treatment. The resulting Fe-NCNP-CNF exhibits excellent catalytic activity, durability, andmethanol tolerance for the oxygen reduction reaction (ORR) in an alkaline solution. The enhanced ORR activity of Fe-N-CNP-CNF can reasonably be attributed to the synergistic contributions provided by a high degree of graphitization of CNF, meso/macroporosity of CNP, presence of catalytically active sites for ORR (i.e., graphitic N and Fe-N bond), and existence of carbon-encapsulated Fe/Fe3C particles.
