Photocatalytic overall water splitting under visible light by TaON and WO3 with an IO3-/I- shuttle redox mediator.
Photocatalytic water splitting into H2 and O2 under visible-light irradiation (lambda > 420 nm) is demonstrated using the oxynitride Pt-TaON for H2 evolution and a Pt-WO3 catalyst for O2 evolution in an IO3-/I- shuttle redox-mediated system.
