Development of visible-light-responsive Ir and La-codoped KTaO3 photocatalysts for water splitting.

Ir and La-codoped KTaO3 has arisen as a novel powdered photocatalyst responding to visible light up to a wavelength of 600 nm. RhCrO3-loaded KTaO3 codoped with Ir and La splits water into H2 and O2 under visible light irradiation.
