| Outline of Final Research Achievements |
Photochemical enzymatic synthesis has received considerable attention for artificial photosynthesis. In this work, the preparation of novel photoactive organic-inorganic hybrid microcapsules with photosensitizer and enzyme for visible-light driven photoenzymatic synthesis was studied. In this system, light energy converts to chemical energy though a visible-light induced electron-transfer (ET) from excited zinc tetraphenyl-porphyrin (ZnTPP) located in an capsule shell to a redox enzyme inside the capsule with the assistance of methyl viologen (MV) as an electron mediator. Consequently, higher encapsulation yield of enzyme was achieved by alginate and 3-(2-aminoethylamino)propyltrimethoxysilane based capsules, and the formate was formed from carbon dioxide. Also, using kappa-carrageenan and 3-aminopropyltriethoxysilane based capsules followed by the crosslinking with glutaraldehyde had the reusability and the experimental results suggested the formation of a small amount of methanol.
