“…Recently, a water-splitting photocatalysts {Cu I 24 (μ 3 -Cl) 8 (μ 4 -Cl) 6 }-based POM@MOF (ZZULI-1) was reported for both H 2 and O 2 production. [131] Its reductionoxidation characteristic of {Cu I 24 (μ 3 -Cl) 8 (μ 4 -Cl) 6 } and two types of POM constitutes resulted in the effective charge transport during photocatalytic reaction, leading to the high H 2 evolution rate of 6614 μmol g À 1 h À 1 and O 2 evolution rate of 1032 μmol g À 1 (calculated for the first 6 min).…”

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.

Polyoxometalates (POMs) are a family of anionic metal-oxo clusters, attracting much attention based on their unique structures and remarkable properties. POM is one type of widely used catalyst owing to their special features of excellent thermal stability, strong redox activity, and multi-electron transfer and storage properties. Cyclometalated units of Ru(N^N) 3 and Ir(C^N) 2 (N^N) have intriguing photo physicochemical properties, such as strong photo-absorption and long excited state lifetime, thus playing an important role in photocatalysis. In the past decade, the photocatalysis system incorporating Ru (Ir)-photosensitizers and POMs received rapid development. In this review, the coupled modes of Ru (Ir)-photosensitizer and POMs were classified into four categories, and the future development was prospected as well.

“…Since the capacity of carbon materials depends on the amounts of electrostatic charges stored at the interfaces of the electrodes and electrolytes, a lot of researches have been done to design the desired carbon materials for ions storage. Tailoring the hierarchical pore structure to match the appropriate electrolyte ions is an effective method to achieve large capacitance, efficient ion diffusion, and charge transfer (Zhu et al, 2011;Fang et al, 2012;Chen et al, 2016Chen et al, , 2017Yu et al, 2016;Liu et al, 2017;Shi et al, 2017Shi et al, , 2019.…”

Tuning hierarchical pore structure of carbon materials is an effective way to achieve high energy density under high power density of carbon-based supercapacitors. However, at present, most of methods for regulating pores of carbon materials are too complicated to be achieved. In this work, a durian shell derived porous carbon (DSPC) with abundant porous is prepared through chemical activation as a defect strategy. Hierarchical porous structure can largely enhance the transfer rate of electron/ion. Furthermore, DSPC with multiple porous structure exhibits excellent properties when utilized as electrode materials for electric double layer capacitors (EDLCs), delivering a specific capacitance of 321 F g −1 at 0.5 A g −1 in aqueous electrolyte. Remarkably, a high energy density of 27.7 Wh kg −1 is obtained at 675 W kg −1 in an organic two-electrode device. And large capacity can be remained even at high charge/discharge rate. Significantly, hierarchical porous structure allows efficient ion diffusion and charge transfer, resulting in a prominent cycling stability. This work is looking forward to providing a promising strategy to prepare hierarchical porous carbon-based materials for supercapacitors with ultrafast electron/ion transport.
