Abstract

Wasser zu Sauerstoff: Ein System für die molekulare elektrokatalytische Wasseroxidation wurde durch Immobilisierung von Monoiridiumkomplexen (siehe Bild; L=PO3H2 oder COOH) auf einer Oberfläche aus Indiumzinnoxid (ITO) erhalten. Dieses System imitiert das Photosystem II, da es hohe Umsatzraten von Sauerstoff aufweist. Für O2 zeigt der Katalysator bei der elektrochemischen katalytischen Wasserspaltung Umsatzraten über 210 000 und Umsatzfrequenzen über 6.7 s−1.
