| 제목 | Photosynthesis of formic acid using N doped TiO2 in vitreous reactor |
| 초록 | Recently CCS- Carbon Capture and Sequestration became an ultimate task. In this study we report on artificial photosynthesis of aminocompounds e.g. amides using artificial photosynthesis technology. We tried to fabricate formic acid, because it has attracted much of interest due to potential using in Direct-formic acid fuel cells etc. Photosynthesized formic can be used as the hydrogen carrier because it is liquid at standard temperature and pressure. It is much safer and easier for handling and storing than hydrogen. It can be directly fed to the fuel cell and not need to be reformed. Formic acid was artificially photosynthesized in photocatalytical reactor using N doped TiO2 and water was used as a hydrogen source in this research. CO2 was introduced using continuous bubbler. The highest formic acid yield was obtained at 300W visible light irradiation using 3g/L photocatalyst load and 3L/min CO2 gas flow rate during continuous stirring. HNO3 provided nitrogen ions supplied for reaction. It was found that N doped TiO2 is much more efficient for artificial photosynthesis of amides than bare one. Samples were analyzed using High Performance Liquid Chromatography, IR spectroscopy and UV-spectroscopy.
