The development of an Ir and Sr-codoped KNbO3 photocatalyst as an O2-evolving photocatalyst for Z-schematic water splitting under visible light irradiation

Ir and Sr-codoped KNbO3 has been found to be a novel photocatalyst for sacrificial O-2 evolution under visible light irradiation. The Ir and Sr-codoped KNbO3 developed worked as an O-2-evolving photocatalyst for Z-schematic water splitting under visible light irradiation when Ru-loaded SrTiO3 doped with Rh was employed as a H-2-evolving photocatalyst.

Automated summary

Ir and Sr-codoped KNbO3 is a new photocatalyst that can generate O2 under visible light irradiation, and it works in conjunction with other photocatalysts for Z-schematic water splitting.
