N-Doped Porous Carbon-Nanofiber-Supported Fe₃C/Fe₂O₃ Nanoparticles as Anode for High-Performance Supercapacitors.

ABSTRACT: Exploring anode materials with an excellent electrochemical performance is of great significance for supercapacitor applications. In this work, a N-doped-carbon-nanofiber (NCNF)-supported Fe₃C/Fe₂O₃ nanoparticle (NCFCO) composite was synthesized via the facile carbonizing and subsequent annealing of electrospinning nanofibers containing an Fe source. In the hybrid structure, the porous carbon nanofibers used as a substrate could provide fast electron and ion transport for the Faradic reactions of Fe₃C/Fe₂O₃ during charge-discharge cycling. The as-obtained NCFCO yields a high specific capacitance of 590.1 F g^-1 at 2 A g^-1, superior to that of NCNF-supported Fe₃C nanoparticles (NCFC, 261.7 F g<
