DescriptionSolar energy is abundant and renewable energy resource. Many approaches have been developed for solar energy conversion to the energy matters that we can use. To utilize the solar energy in a large scale, it is necessary to develop a technology to cover a large area where sunlight reaches and to convert into storable and transportable energy, i.e. chemical energy. Water splitting to generate hydrogen is one of the most attractive candidates for the purpose. In this event, photocatalytic water splitting on photocatalysts will be discussed in detail comparing with other methods of hydrogen generation from water.
Kazunari Domen received B.S. (1976), M.S. (1979), and Ph.D. (1982) honors in chemistry from the University of Tokyo. He joined Chemical Resources Laboratory, Tokyo Institute of Technology in 1982 as Assistant Professor and was subsequently promoted to Associate Professor in 1990 and Professor in 1996. He moved to the University of Tokyo, Department of Chemical System Engineering as Professor in 2004. He is now an associate editor of Chemical Science, Royal Society of Chemistry. He also was an associate editor of Catalysis Today and Chemistry Letters. He received Catalysis Society of Japan Awards 2007. He has published more than 500 original papers and about 100 reviews and accounts in the field of heterogeneous catalysis, especially of water splitting reaction on photocatalysts. Kazunari Domen has been working on overall water splitting reaction on heterogeneous photocatalysts to generate clean and recyclable hydrogen. Domen started investigation on non-oxide type photocatalysts to extend responsible wavelength of light into visible region, and in 2005, he has indeed succeeded in accomplishing overall water splitting under visible light (400 nm<λ<500nm) on a GaN:ZnO solid solution photocatalyst. This is the first reliable and reproducible system for overall water splitting under visible light irradiation on a particulate photocatalyst.
