Z-scheme overall water splitting on modified-TaON photocatalysts under visible light (λ<500 nm)

Overall water splitting was accomplished using a RuO2-TaON and Pt-TaON mixture with IO3/I- redox couple under visible light (lambda < 500nm). This is the first example of overall water splitting based on an oxynitride photocatalyst including a transition-metal element with do-electronic configuration.
