Zinc and Titanium Spinel Oxynitride (ZnxTiOyNz) as a d0–d10 Complex Photocatalyst with Visible Light Activity

Abstract The spinel-type oxynitride of zinc and titanium (ZnxTiOyNz) reduces H+ to H2 and oxidizes H2O to O2 in the presence of a sacrificial electron donor and acceptor under visible light irradiation (λ > 420 nm). ZnxTiOyNz is a d0–d10 complex oxynitride photocatalyst that has the potential to be active for water splitting under visible light.
