The possibility of a new iron‐based catalytic site for the oxygen reduction reaction, comprising outer graphitic layers encasing a Fe 3 C core, is discussed in the context of iron‐based catalysts for proton‐exchange membrane fuel cells. Further analysis of new Fe 3 C‐700 and S2‐700 catalysts is still needed to determine the relationship between the active sites and oxygen reduction activity.
