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
