Novel water-splitting photocatalyst operable over wide range of the visible light spectrum

Clean renewable energy can be produced by photocatalytically splitting water into hydrogen and oxygen with solar energy. Most of the conventionally developed water-splitting photocatalysts, however, were only active under UV irradiation, and only a few have been demonstrated to operate under visible light, at up to 500 nm. For making high-efficiency use of solar energy, it was necessary to develop a photocatalyst that can utilize longer wavelength light. Scientists have now developed a water-splitting photocatalyst that is operable over a wider range of the visible light spectrum than before.
