Development of photocatalysts for artificial photosynthesis
Details of the Initiative
Our laboratory aims to develop photocatalysts to realize artificial photosynthesis. Photosynthesis in green plants uses light energy to produce high-energy substances (such as sugars) from water and carbon dioxide. Therefore, artificial photosynthesis can be broadly defined as the artificial creation of high-energy materials using the energy of light. From this point of view, the production of hydrogen from water and the recycling of carbon dioxide using photocatalysts can be called artificial photosynthesis.
In simple terms, photocatalysts are compounds that absorb light and cause redox reactions. In our research, we deal with inorganic semiconductors as photocatalyst materials, and work on the development of photocatalysts that can efficiently utilize light of a wide range of wavelengths in the solar spectrum.
Fossil fuels such as coal and oil are also stored solar energy from ancient times. After all, humans depend on solar energy for their lives. Artificial photosynthesis can be said to be a science and technology that can contribute to global energy and environmental problems by actively using solar energy in the present. The practical application of artificial photosynthesis will bring us closer to the realization of a sustainable society.
