One of the simplest methods for splitting water into H2 and O2 with solar energy entails the use of a particulate‐type semiconductor photocatalyst. To harness solar energy efficiently, a new water‐splitting photocatalyst that is active over a wider range of the visible spectrum has been developed. In particular, a complex perovskite‐type oxynitride, LaMgxTa1−xO1+3xN2−3x (x≥1/3), can be employed for...
Wasserspaltung mit einem partikelförmigen Photokatalysator unter Verwendung von Solarenergie stellt eine skalierbare und kostengünstige Methode zur Herstellung von Wasserstoff dar. Allerdings verwenden die meisten der bislang entwickelten Photokatalysatoren nur einen geringen Teil des Sonnenspektrums. In ihrer Zuschrift auf S. 2998 ff. beschreiben T. Takata, K. Domen et al. einen neuartigen Photokatalysator...
