In article number 1906174, Jia Li, Lin Gan, Feiyu Kang, and co‐workers report the direct growth of carbon nanotubes doped with Fe‐N 4 moieties for improved electrocatalytic stability in the cathodic oxygen reduction reaction (ORR) in proton‐exchange‐membrane fuel cells. By increasing the neighboring graphitic nitrogen, the Fe‐N 4 moieties also show enhanced activity due to the modified spin state of the Fe center and thereby optimized binding energy with ORR intermediates.
