| Research Abstract |
In the artificial leaf, one of the artificial photosynthesis systems, reverse reaction does not happen due to its two-dimensional separation of the redox reactions. The research project has a aim to design artificial organic leaves system for photocatalytic water splitting using only visible light based on our previous study of polymer film type organophotocatalyis of volatile molecules oxidation.
We have succeeded the layering of p-and n-type organic semiconductors on the precisely synthesized block copolymer membrane and investigated its photoelectrochemical behaviors as follows. 1) The optimized temperature of the substances transport in the hydrophilic channel was found to be relatively higher than the room temperature. 2) The temperature dependent photooxidation rate was evaluated for the p-n junction. Furthermore, we have submitted new concept of the one-path flow reactor of organophotocatalyst where the optimized absorbance of each layer was evaluated for the first time.
