Density functional theory study of the oxygen evolution activity on SrTaON surfaces
Maria Bouri, Ulrich Aschauer
Solar water splitting has attracted much attention as a clean and renewable route to produce hydrogen fuel. Since the oxygen evolution half-reaction (OER) requires high overpotenti…
Nitrogen loss and oxygen evolution reaction activity of perovskite oxynitrides
Hassan Ouhbi, Ulrich Aschauer
Perovskite oxynitride photocatalysts were reported by experiment to evolve small amounts of N due to the self-oxidation of nitrogen ions by photo-generated holes. The N evo…
Water oxidation catalysis on reconstructed NaTaO (001) surfaces
Hassan Ouhbi, Ulrich Aschauer
Polar perovskite oxide surfaces are subject to structural reconstruction as a possible stabilisation mechanisms, which changes the surface structure and hence the surface chemistry…
Band-gap engineering in AB(OS) perovskite oxysulfides: A route to strongly polar materials for photocatalytic water splitting
Nathalie Vonrüti, Ulrich Aschauer
Polar heterogeneous photocatalysts were shown to lead to enhanced charge-carrier separation that results in superior activity for example for photocatalytic water splitting. Promis…
LaTiOxNy thin film model systems for photocatalytic water splitting: physicochemical evolution of the solid-liquid interface and the role of the crystallographic orientation
Markus Pichler, Wenping Si, Fatima Haydous +10
The size of the band gap and the energy position of the band edges make several oxynitride semiconductors promising candidates for efficient hydrogen and oxygen production under so…
