– The first ever successful water oxidation with a near-infrared light irradiation achieved by light harvesting induced at gold nanostructured optical antennae.
– Expected developments in artificial photosynthesis using visible light and near-infrared light.
|Overview||Professor Hiroaki Misawa’s research group at the Hokkaido University Research Institute for Electronic Science successfully fabricated gold nanostructures/titanium dioxide photoelectrodes capable of the photoelectric conversion of a wide spectral range, namely the ultraviolet, visible light, and near-infrared wavelengths, and made progress toward artificial photosynthesis systems, which are gaining attention, not only for photoelectric conversion but also for the ultimate light-energy conversion system.
As a result, with regard to the water oxidation crucial in artificial photosynthesis systems, the research group succeeded in creating the world’s first system that involves oxygen and hydrogen peroxide using not just visible light but also near-infrared light.
