摘要： Platinfreies Chelat-Katalysatormaterial wird für die selektive Sauerstoffreduktion bei Wasserstoff- und Methanol- Brennstoffzellen, beispielsweise in der Autoindustrie, eingesetzt. Die erreichbare Porosität und die katalytische Aktivität sind aufgrund von Sintereffekten während der Hochtemperaturbehandlung bei der Herstellung für kommerzielle Anwendungen nicht ausreichend. Das erfindungsgemäße Verfahren ist deshalb gekennzeichnet gekennzeichnet durch eine Niedertemperatur-Plasmabehandlung des pulverförmigen Übergangsmetallchelats in einem Plasmareaktorraum mit einem inerten Plasmagas mit einer solchen Wahl von Plasmaleistung, Plasmagasdruck, Plasmainitialisierung und Behandlungszeit, dass die Moleküle des Übergangsmetallchelats im Plasma fragmentiert werden und in einer chemischen Folgereaktion so vernetzen, dass sich einerseits die Kohlen- stoffmatrix ausbildet, andererseits aber die Chelat-Grundstruktur in der Umgebung des Übergangsmetalls erhalten bleibt. Die erzeugten Chelat- Katalysatorpartikel sind hochporös und weisen eine Größe im Bereich von 0,06 μm auf. Das so erzeugte Zwischenprodukt kann durch eine kombinierte Sputter-Plasma-Behandlung mit zwei verschiedenen Niedertemperaturplasmen unterschiedlicher Leistungen, die parallel oder alternierend betrieben werden, zu einer elektrokatalytischen Beschichtung als Endprodukt, insbesondere in der Anwendung auf einer Gasdiffusionselektrode, weiterverarbeitet werden.
