Direct Water Splitting into Hydrogen and Oxygen under Visible Light by using Modified TaON Photocatalysts with d0 Electronic Configuration

Parting water! Direct splitting of pure water into H2 and O2 under visible light (λ>400 nm) was achieved by using a modified TaON photocatalyst with d0 electronic configuration. Modification of a less-defective TaON (ZrO2/TaON) with core/shell-structured RuOx/Cr2O3 nanoparticles and colloidal IrO2 was found to be indispensable to achieving the reaction (see figure).
