In order to carry out water splitting using solar energy, the materials used should absorb visible light and have appropriate conduction band levels to allow the  production of H₂.

Abe and coworkers have made TaON and Ta₃N₅ photoanodes displaying high photocurrent which represent an exciting step towards this goal.
