Abstract

Harmonische Zusammenarbeit: Nanopartikel aus Mn₃O₄ und aus Kern/Schale‐strukturiertem Rh/Cr₂O₃ als Cokatalysatoren auf der Oberfläche eines GaN‐ZnO‐Mischkristalls als Katalysator beschleunigen die O₂‐ bzw. H₂‐Entwicklung unter sichtbarem Licht (λ>420 nm) und verbessern so die Wasserspaltungsaktivität gegenüber analogen Systemen, die nur mit Mn₃O₄ oder Rh/Cr₂O₃ modifiziert wurden.
