| Outline of Final Research Achievements |
In order to improve the photocatalytic property of oxide photocatalysts and clarify the mechanism, important information were acquired through the investigations of following four points. Firstly, apparent quantum yield and the reaction mechanism of electron and hole produced in Ga2O3 photocatalyst under the overall H2O splitting was examined on the basis of the intensity of irradiated light dependence of the phtocatalytic reaction. Secondly, optimization of the preparation condition of mixed oxide photocatalysts by polymerizable complex method, one of the effective preparation methods for oxide photocatalysts, to the overall H2O splitting was examined. Thirdly, the detailed condition of the improvement of photocatalytic performance of SrTiO3 by the addition of metal ions to the overall H2O splitting was examined to clarify the state of SrTiO3 by the addition of metal ion. Fourthly, the effects of metal ion addition to In2O3 photocatalyst to the photo-oxidation of H2O were examined.
