Water splitting based on first‐row transition metal (3d) photocatalysts is a cost‐effective technology for the conversion of abundant solar energy into useful energy on a large scale. The catalytic core of photosynthetic enzymes is a cubic CaMn4O5 cluster. Illuminated by natural photosynthesis, artificial solar water splitting photocatalysts composed of metal clusters are now being designed and tested. Ideally, such photocatalysts composed of atomically precise metal clusters with regular crystal structures are promising model catalysts that can be used to study structure–performance relationships. Recent advances based on metal cluster designs have improved our understanding of photoinduced charge separation and catalytic water redox reactions. This Minireview summarizes the recent advances in 3d metal cluster photocatalysts with well‐defined structures for photocatalytic water splitting and focuses on different clusters with tunable structures that are capable of achieving better photocatalytic properties.

“…In spite of heterogeneous WOCs are easily obtained on a large scale and conveniently reused, homogeneous molecular water oxidation catalysts attract increasing attention for the advantages of high catalytic efficiencies, advantages in mechanism research and easy modification in structures . In the past decades, molecular catalysts were mainly applied to the dye‐sensitized systems containing molecular [Ru(bpy) 3 ] 2+ (bpy=2,2′‐bipyridine) or its derivatives as light harvester . A large number of transition‐metal (Fe, Co, Ni, Cu, Mn, Ru) substituted molecular catalysts were demonstrated to be excellent WOCs in molecular light harvester systems under visible light illumination.…”

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.[a] Dr.

Reactions of bis(methylthioether)pyridine (btep) with CuX 2 (X = Br and Cl) form two new complexes, [Cu(btep)Br 2 ] and [Cu(btep)Cl 2 ], respectively, which have been determined by X-ray crystallography. Both of them can serve as catalysts for electrochemical and photochemical driven hydrogen evolution. Under an overpotential (OP) of 837.6 mV, [Cu(btep)Br 2 ] or [Cu(btep)Cl 2 ] can electrocatalyze hydrogen evolution from a neutral water with a turnover frequency (TOF) of 373 and 120 mol of hydrogen per mole of catalyst per hour (mol H 2 /mol catalyst/h), respectively. Under blue light, mixing with CdS nanorods (CdS NRs) as a photosensitizer, and ascorbic acid (H 2 A) as a sacrificial electron donor, the photolysis of an aqueous solution (pH 4.5) with [Cu (btep)Br 2 ] or [Cu(btep)Cl 2 ] can provide 6180 and 5120 mol of H 2 per mole of catalyst (mol of H 2 (mol of cat) −1 ) during 48-h irradiation with an average apparent quantum yield of 16.7% and 11.0%, respectively. The results show that [Cu(btep)Br 2 ] shows a more efficient activity for H 2 generation than [Cu (btep)Cl 2 ]. Several electrochemical and photochemical measurements and analysis are carried out to study catalytic mechanism for H 2 production.
