It's all in the detail : Highly active Fe/N/C catalysts for the oxygen‐reduction reaction in polymer‐electrolyte‐membrane (PEM) fuel cells can be obtained from a precursor constructed from the zeolitic imidazolate framework ZIF‐8 and an iron–ligand complex if, and only if, the displacement of Zn II ions from ZIF‐8 by Fe II ions is restricted (see picture; TPTZ=2,4,6‐tris(2‐pyridyl)‐ s ‐triazine).
