Abstract

Abstract: 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. Abstract : Artificial photosynthesis : Water oxidation is kinetically demanding; therefore, efficient systems for visible‐light‐driven water oxidation are required. Since 2009, photoelectrochemical devices using visible light have been extensively investigated for water oxidation. Recent progress in visible‐light‐driven molecular water oxidation and the challenges in the field including interfacial recombination and the restricted use of visible light of over 500 nm are discussed.
