Effizient und erschwinglich: Forscher entwickeln Katalysatormaterial für Brennstoffzellen

Platin-Nickel-Nanooktaeder sparen 90 Prozent Platin

(PresseBox) (Jülich, )
Leistungsfähige, robuste und günstige Katalysatormaterialien sind ein Schlüssel zum Durchbruch der Brennstoffzelltechnologie. Ein Material für die Umwandlung von Wasserstoff und Sauerstoff zu Wasser, das mit einem Zehntel der bisher typischen Menge Platin auskommt, entwickelten nun Wissenschaftler aus Jülich und Berlin. Mit Hilfe modernster Elektronenmikroskopie fanden die Forscher dabei heraus, dass die Funktion der nanometerkleinen Katalysatorpartikel entscheidend durch ihre geometrische Form und die atomare Struktur bestimmt wird. Diese Erkenntnis zeigt neue Wege auf, Katalysatoren für die Energieumwandlung und -speicherung weiter zu verbessern. Nachzulesen ist dies in der aktuellen Ausgabe der renommierten Fachzeitschrift Nature Materials (DOI: 10.1038/nmat3668).
