Isolierte Eisenatome die durch Pyrolyse einer verkapselten Vorstufe erzeugt wurden, katalysieren die Sauerstoffreduktion (ORR) in hoch reaktiver und stabiler Weise. In ihrer Zuschrift auf S. 7041 ff. zeigen D. Wang, Y. Li und Mitarbeiter experimentell und durch Rechnungen, dass das Vorliegen der isolierten Fe‐Atome und die Einführung von Stickstoff entscheidend für die ORR‐Aktivität sind.
The development of low‐cost, efficient, and stable electrocatalysts for the oxygen reduction reaction (ORR) is desirable but remains a great challenge. Herein, we made a highly reactive and stable isolated single‐atom Fe/N‐doped porous carbon (ISA Fe/CN) catalyst with Fe loading up to 2.16 wt %. The catalyst showed excellent ORR performance with a half‐wave potential (E1/2) of 0.900 V, which outperformed...
