| Outline of Final Research Achievements |
In this study, we focused on the reaction process of natural photosynthesis and aimed at constructing a solar water splitting accompanied with electric power storage using powdered photocatalysts. The most important issue was the extremely low efficiency of the oxygen production reaction using a Co(bpy)3 complex ion. We succeeded in improving the performance more than one order by developing the preparation method to improve crystallinity, and an appropriate treatment agent. Furthermore, we clarified a condition that electricity can be efficiently extracted by combining vanadium(V) and Co(bpy)3 complex ions. Finally, we have succeeded in constructing a photocatalytic reaction system which can obtain hydrogen and electricity simultaneously utilizing solar energy.
