| Outline of Final Research Achievements |
Improvement of next generation catalysts requires understanding catalytic properties of already exist catalyst in atomic level. Catalytic property of metal alloy heterogeneous catalysts depends on various factors including size, internal structure and electronic properties. One approach to understand the complicated property is to make system simple. For case of catalyst, utilizing atomically well defined single crystal surface as catalyst support will be good solution. The present research experimentally revealed the surface structure of TiO2(110)-1x2 structure, which is known to expose low coordinated Ti species. The catalyst supported by the low coordinated structure is expected to show specific catalysis. The new type of defect structure in TiO2 is also revealed.
