Recent Progress in Visible Light Driven Water Oxidation Using Semiconductors Coupled with Molecular Catalysts

Hybrid systems combining the molecular catalyst and semiconductors have been demonstrated to be feasible and efficient for water oxidation under visible light illumination. Herein, we present a brief review on recent developments of constructing molecule/semiconductor hybrid systems. These hybrid systems combined molecular catalysts with dye‐sensitized semiconductors or visible‐light‐response semiconductors. This review systematically summarizes the fabrication strategies of hybrid systems in photoelectrochemical (PEC) water splitting and powdered photocatalytic water oxidation. Furthermore, we highlight the excellent water oxidation performances and stability of different hybrid systems and provide valuable guidance to design construction strategies for more robust and capable devices.
