"Overall Water Splitting On Some Oxynitride-Based Photocatalysts"

Presented by Kazunari Domen, University of Tokyo, Japan

Thursday, July 31, 2008, 10:00 am — Hamilton Seminar Room, Bldg. 555

Abstract: Water splitting to form hydrogen and oxygen with solar energy is one of the attractive candidates for clean and sustainable energy production. Some oxynitrides work as visible light responsive photocatalysts for overall water splitting with proper modifications. GaN:ZnO and ZnGeN2:ZnO solid solutions with core-shell type hydrogen evolution sites will be discussed in detail. In addition, two-step photo-excitation systems for overall water splitting under visible light with the wavelengths longer than 600 nm will be introduced.
