Artificial photosynthetic systems. Using light and water to provide electrons and protons for the synthesis of a fuel

This review covers the progress achieved in the synthesis and characterization of different metal based catalysts designed for the photocatalytic oxidation of water with special focus on molecular designed systems. In those cases where the mechanism of the light-driven catalytic activity of these complexes is not known, we have looked to published mechanisms related to chemically activated catalysts. We also discuss the choice of the chromophores used to sensitize these reactions as well as the recovery of the reaction products and nature of the electron acceptors used.
