Nitrogen-enriched core-shell structured Fe/Fe(3)C-C nanorods as advanced electrocatalysts for oxygen reduction reaction

Adv Mater. 2012 Mar 15;24(11):1399-404. doi: 10.1002/adma.201104392. Epub 2012 Feb 6.


A cost-effective route for the preparation of Fe(3) C-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(3)C@C features an ultralow cost and excellent long-term stability suitable for mass production.
