Abstract

original image

Was spaltet Wasser? Zwei Lithiumcobaltoxid-Polymorphe – ein nanokristalliner kubischer Spinell und eine rhomboedrische Schichtstruktur – wurden erzeugt und in der photokatalytischen Wasseroxidation getestet (siehe Schema). Als entscheidend für die Aktivität der unterschiedlichen Phasen erwies sich das Vorliegen eines würfelförmigen Co4O4-Motivs, das in der kubischen Form des Katalysators vorhanden war, der Schichtstruktur hingegen fehlte.
