Artificial photosynthetic cycle

The implementation of an artificial photosynthetic cycle which could recycle C02 [4, 5], thus complementing the natural cycle, could also make an effective contribution to reducing C02 emissions. 

Water and carbon dioxide provide the most attractive and abundant source materials for the fuel products of an artificial photosynthetic device, as seen in Fig. 11. These two compounds are the outcome of the heterotrophic cycle providing the energy sources of the living organism, and the result of consumption of fossil fuels by mankind. Not surprisingly, both of the materials exhibit high chemical... 

Non-Forster fluorescence quenching of trans-etiochlorin by magnesium oc-taethylporphine in phosphatidylcholine vesicles gives evidence for a statistical pair energy trap. Energy transfer also occurs in the excited singlet manifold of chlorophyll. " The photophysics of bis(chlorophyll)-cyclophanes, models of photosynthetic reaction centres, have been explored for use in artificial photosynthesis.Picosecond time-resolved energy transfer in phycobilosomes have also been studied with a tunable laser. The effect of pH on photoreaction cycles of bacteriorhodopsin, " the fluorescence polarization spectra of cells, chromatophores, and chromatophore fractions of Rhodospirillum rubrum, and a brief review of the mechanism and application of artifical photosynthesis are all relevant to the subject of this Chapter.
