模拟光合作用分解水制氢是将太阳能转换为化学能的有效途径,基于光驱动水氧化的有机底物氧化是模拟光合作用体系Ⅱ释氧中心(OEC)的新思路.该反应过程是通过金属催化剂将水分子活化生成以水为氧源的高价金属-氧中间体,随后将氧原子转移给有机底物,在此过程中水中的氢源得以释放.从催化剂的角度总结了近年来光驱动水分子活化的研究进展,同时对基于光驱动水氧化的有机底物氧化与光致产氢结合进而建立新型光分解水制氢的体系提出展望.

Hydrogen production by artificial photosynthetic water splitting is an efficient approach to convert solar ennergy into chemical bonds. Oxygenation of an organic substrate based on light-driven water oxidation is innovative way to mimic the oxygen evolving center (OEC) in Photosystem Ⅱ. The metal catalyst will accomplish H2O activation to generate high valent metal-oxo intermediate, which can transfer the oxygen atom to an organic substrate, during which the H atoms in H2O molecule could be released. This review is a perspective of the recent advances in oxygenation of organic substrates with water as oxygen source. In the meanwhile, research prospect on photocatalytic hydrogen production coupled with the photocatalytic oxygenation of an organic substrate for a new water splitting system has been proposed.

Key words: artificial photosynthesis, water molecule activation, metal-oxo intermediate, oxygenation of organic substrates
