Development of Ir and La-codoped BaTa2O6 photocatalysts using visible light up to 640 nm as an H2-evolving photocatalyst for Z-schematic water splitting

Abstract

Ir and La-codoped BaTa₂O₆ was developed as a novel photocatalyst for H₂ evolution utilizing visible light up to 640 nm. The Ir and La-codoped BaTa₂O₆ with a Ru cocatalyst functioned as an H₂-evolving photocatalyst for Z-schematic water splitting under visible light irradiation upon combination with a BiVO₄ O₂-evolving photocatalyst and a [Co(bpy)₃]^3+/2+ electron mediator.
