Abstract

A cost-effective route for the preparation of Fe 3C-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 R ex of 1 Ω) than the Pt/C in microbial fuel cells. Furthermore, the N-Fe/Fe 3C@C features an ultralow cost and excellent long-term stability suitable for mass production.
