Abstract

The porous oxynitride TaON film electrode prepared on conducting glass (FTO) showed significantly high quantum efficiency (IPCE = ca. 76% at 400 nm at 0.6 V vs Ag/AgCl) in an aqueous Na₂SO₄ solution, after loading of IrO₂̇nH₂O nanoparticles as a cocatalyst for water oxidation. Overall water splitting into H₂ and O₂ under visible light was demonstrated using an IrO₂·nH ₂O-loaded TaON photoanode combined with a Pt electrode under an externally applied bias (0.6-1 V).
