Artificial photosynthesis is of great importance in the production of clean fuels such as hydrogen from sunlight and water. In such systems, water oxidation is kinetically demanding; therefore, efficient catalysts and systems for water oxidation are required. Among the artificial systems, photosynthesis has been recently developed owing to the emergence of efficient molecular catalysts for water oxidation. This Review highlights several important concepts including electron transfer and catalysis, and the representative systems of molecular systems for visible-light-driven water oxidation. In addition, the remaining challenges in this field, including the interfacial recombination and the restricted utilization of visible light of over 500 nm, are discussed.
人工光合作用对于利用阳光和水生产清洁燃料（如氢气）极为重要。在这类体系中，水氧化在动力学上要求较高；因此，需要高效的水氧化催化剂和体系。在人工体系中，由于出现了高效的水氧化分子催化剂，光合作用近来得到了发展。本综述重点介绍了几个重要概念，包括电子转移和催化作用，以及用于可见光驱动水氧化的分子体系的代表性体系。此外，还讨论了该领域仍然存在的挑战，包括界面复合以及对波长超过500 nm的可见光利用受限的问题。
