    报告摘要Artificial photosynthesis is urgently required in order to solve global energy and environmental issues. This lecture focuses on the past and future of artificial photosynthesis.1 Artificial photosynthesis consists of five units: (1) the light–harvesting (LH) unit, (2) the charge–separation (CS) unit, (3) the catalytic unit for water reduction, (4) the catalytic unit for water oxidation, and (5) the catalytic CO2 fixation unit. We have developed a variety of photosynthetic reaction center models composed of organic electron donors and acceptors linked by covalent or non-covalent bonding, which undergo efficient charge separation and slow charge recombination.2 The efficient charge-separation step has been successfully combined with the catalytic water reduction step with earth-abundant metal catalysts to develop efficient photocatalytic hydrogen evolution systems.3,4 Efficient CO2 reduction catalysts have also been developed.5 The photocatalytic oxidation of water with O2 in the air to produce H2O2 has been achieved,6-8 together with the development of one-compartment H2O2 fuel cells.9-10 The photocatalytic oxidation of water with O2 in the air was found to be enhanced significantly in seawater.11 Thus, the combination of the photocatalytic H2O2 production from seawater and O2 using solar energy with one-compartment H2O2 fuel cells provides on-site production and usage of H2O2 as a more useful and promising liquid solar fuel than H2.11,12 The solar-driven oxidation of H2O by O2 to produce H2O2 has also been combined with catalytic oxidation of benzene by H2O2 to produce phenol, when the overall reaction is solar-driven hydroxylation of benzene by O2, which is the greenest oxidant, with H2O that is the greenest reductant.13 The first functional mimic of Photosystem II (PSII) is also discussed together with the future combination with a PSI mimic.14
