Nitrogen‐Enriched Core‐Shell Structured Fe/Fe₃C‐C Nanorods as Advanced Electrocatalysts for Oxygen Reduction Reaction

Abstract

A cost-effective route for the preparation of Fe3C-based core-shell structured catalysts for oxygen reduction reactions was developed. The novel catalysts generated a much higher power density (i.e., three times higher at Rex of 1 Ω) than the Pt/C in microbial fuel cells. Furthermore, the N-Fe/Fe3[email protected] features an ultralow cost and excellent long-term stability suitable for mass production.
