Carbon nanotubes (CNTs) are corrosion resistant supports for electrochemical applications. A surface functionalization of CNTs prior to pyrolysis enables improved interaction with carbon frames hosting FeN 4 moieties: higher site densities and turn‐over frequencies are reached. Together with the good cycling stability during accelerated stress tests, this makes Fe–N–C catalysts of interest for integration in proton‐exchange fuel cells (PEFCs).
