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 O) 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.
