| Outline of Final Research Achievements |
In order to facilitate the endothermic reaction of the IS process with light energy, we investigated the photocatalytic activity of semiconductor materials for HI decomposition. It was found that Rh-substituted SrTiO3 (SrTiO3:Rh) and Co loaded TiO2 nanosheet photocatalysts showed hydrogen production from HI aqueous solution under Xe lamp irradiation. In the case of SrTiO3:Rh photocatalyst, the loading of the noble metal co-catalysts contributed to hydrogen production, and thus the HI photodegradation activity was improved by loading noble metal co-catalysts. It was also found that the co-catalyst suitable for HI photodegradation is important not only for promoting surface reaction but also for durability against HI aqueous solution.
