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

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/Fe3C@...

Zusammenfassung: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/Fe3C@C features an ultralow cost and excellent long‐term stability suitable for mass production.
