Graphical Abstract

Als möglicher Mechanismus der Reduktion von Wasser zu H2 wurde die reduktive Spaltung von Wasser und α-H-Abstraktion schon lange vermutet, bislang konnte aber kein eindeutiges Beispiel geliefert werden. Detaillierte DFT-Rechnungen zeigen nun, dass dieser Prozess an einem MoI-Zentrum energetisch begünstigt ist (siehe Bild). Die Bildung von H2 nach diesem Mechanismus ist auch an einem MoII-Zentrum möglich, allerdings weniger günstig.
