| Outline of Final Research Achievements |
We developed a new powdered photocatalyst consisting of Co(OH)2 and TiO2. It is well known that TiO2 is an active photocatalyst, but only works under UV irradiation. By contrast, the Co(OH)2/TiO2 hybrid photocatalyst is capable of absorbing visible light with wavelengths of up to 850 nm and oxidizing water into oxygen gas, even though it consists of only earth-abundant elements only. To our knowledge, this system provides the first demonstration of a photocatalytic material capable of water oxidation upon excitation by visible light up to such a long wavelength.
