High-performance and durable Fe–N–C fuel cell catalysts

In a recent issue of Nature Catalysis, Zeng et al. reported an exciting iron-nitrogen-carbon (Fe–N–C) catalyst, which was synthesized by introducing an optimal amount of hydrogen gas during the pyrolysis process. The fuel-cell performance and durability of Fe–N–C is comparable to that of a commercial platinum carbon (Pt/C) catalyst. Their astute approach may provide valuable insights into the preparation of Fe–N–C in the future.
