| Outline of Final Research Achievements |
In this research, the suppression effect for undesirable backward reaction has been evaluated using shape controlled photocatalyst particles. As a result, it was found that the reaction selectivity of water and Fe（II) for photo-generated holes is drastically changed depending on the type of the exposed crystal facets, although the Fe（II) oxidation proceeds preferentially instead of the water oxidation due to thermodynamically advantageous. Thus, it has been demonstrated that the control of particle shape can be an efficient method to design high efficient photocatalysts. Moreover, the developments of novel photocatalysts and high performance technologies have been also conducted. We successfully developed various attractive materials.
