| Research Abstract |
This Grant-in-aid for Scientific Research on Priority Areas is aimed at establishing the fundamental theory and technology of energy conversion and material transformation by effective use of light energy. We mainly researched the design development of photo-energy conversion and advanced photocatalyst. We also studied the followings to understand the essence of photofunctional interfaces and to achieve wide development: interfacial structure control and space anisotropy control in nanoscale levels, dynamic behavior elucidation of radical species generated by light irradiation on semiconductors, new measurement methods intended for photofunctional interfaces. The administrative team was organized to smoothly promote these studies. The team hosted meetings and symposiums, clarified the goals and problems that needed to be solved as well as checked the progress of each study, and planned further development.
In 2001, we held a research design public symposium in The University of Tokyo. I

n 2002, we held a 1 general meeting in Nagoya University, and a 2nd general meeting and a 19 public symposium of the findings in The University of Tokyo. In 2003, we held a 1^<st> general meeting in Osaka University, a plan study team meeting in Okinawa, and a 2^<nd> general meeting and a 2^<nd> public symposium of the findings in Keio University We also held an administrative team meeting during the 2^<nd> public symposium, and exchanged opinions about the direction of the whole study for future. In 2004, we held a 1^<st> general meeting in Nagoya University and a 2^<nd> general meeting and a 3^<rd> public symposium of the findings in Keio University At the same time, an administrative team meeting was held in Keio University and exchanged opinions about the direction of each study. In 2005, we held a 1^<st> general meeting in The University of Tokyo, and a 2nd general meeting and a 4th public symposium of the findings in Keio University. In 2006, we held a 1^<st> general meeting in Kanagawa Science Park, and a 2nd public symposium and a 5th public symposium of the findings at Papillon 24 in Fukuoka. In March 2007, we held a public symposium in Tokyo International Forum to summarize the whole study. In 2007, we summarized the whole findings of the study obtained in 2001-2006 by referring to the contents of the presentation at public symposium held in March 2007 in particular. Specifically, the summary of A01 team is mainly based on the result of the contact situation and the charge transfer of an interface having a nanostructure. The summary of A02 team is mainly based on the development of high-sensitivity/visible-light-solicited type titanium oxide and a new material against Down-hill type reaction of titanium oxide photocatalyst, application development for environmental purification and medical scene, and the findings of the oxidation reaction mechanism. The summary of A03 team relates to light measurement technology and light control devices, and is mainly based on results obtained after advancing the functionality and device application. The summary of A04 team relates to designing of a high efficiency visible light sensitization charge separating system, and is mainly based on a result obtained when the system was applied to visible light sensitized decomposition of water. The summary of A05 team clarifies the decomposition mechanism of various kinds of organic materials on photofunctional interfaces, such as titanium oxide photocatalytic reaction, and mainly relates to the reactive property of organic radical ion which is important in titanium oxide photocatalytic reaction. In March 2008, a final accomplishment report including all of the above summaries was made. Less
