Abstract: | The production of chemicals and fuels, or energy-rich compounds, from water by sunlight is described as a particularly attractive
means for the conversion of solar energy to a valuable renewable resource. The redox properties of photoexcited molecules
and the operating mechanism of light-driven systems are first considered. The mechanism of water oxidation carried out by
higher plants and green algae-which is actually one of the most important biochemical reactions—as well as that of artificial
photosystems, up-to-now designed trying to simulate the natural process with higher efficiency and simplicity, are likewise
discussed. A number of biological and chemical light-driven systems are presented as practical ways to solar energy conversion. |
