| Outline of Final Research Achievements |
In this work, the artificial photosynthesis system based on Layered Double Hydroxides (LDHs) was constructed and enhanced its photocatalytic activity by co-catalyst doping, interlayer-anions exchanging, improving LDH crystallinity and composite heteropoly acid (HPA) on LDH surface. By co-catalysts (Ru, Rh) doping into Zn-Cr LDH framework, the photocatalytic activity was enhanced. Then, the preparation and characterization of the interlayer-anions exchanged LDHs, and its photocatalytic activity was investigated and compared with each anions-intercalated LDHs. As a result, it was elucidated which interlayer carbonate was reduced in LDH photocatalytic reaction. By the preparation of LDH/heteropoly acid (HPA) composites, it is considered that preparation of composite was important to improve composite photocatalyst because HPA directly contact on the LDH surface, which favored the transfer and separation of charge carriers.
