Solar powered water splitting moves a step closer

Fabrication schemeIn 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.
