Abstract

Leicht, günstig, effizient: Co3O4-Nanostrukturen (siehe Bild) in mesoporösem Siliciumoxid sind die ersten nanometergroßen Mehrelektronenkatalysatoren mit einem Übergangsmetalloxid der ersten Periode, die Wasser unter Bildung von Sauerstoff effizient spalten. Die sehr große Oberfläche der Nanostabbündel trägt wesentlich zur hohen Umsatzfrequenz bei.
