“…Combining clusters with nanomaterials is a promising method for enhancing the water splitting performance due to the advantages of the intrinsic properties of the individual components . The composite materials not only can regulate the surface electronic structure of nanomaterials but can also improve the charge separation of the electron‐hole pairs because of the heterojunction construction.…”

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.

“…Although chemical modification of semiconductor surfaces can improve rates of photoelectrosynthetic fuel production (Supporting Information Scheme S1a), the addition of colored materials, which include myriad electrocatalysts, can also confer the undesirable effect of reflecting or parasitically absorbing photons before they can reach the underlying semiconductor (Scheme S1b). − ,− ,− …”

The direct integration of electrocatalysts with photovoltaic materials provides a strategy to photoelectrochemically power chemical transformations and store intermittent solar energy as fuels. However, many electrocatalytic components used or proposed for use in such assemblies also absorb visible light. This prompts the questions: to what extent does a selected electrocatalytic coating screen photons from reaching the underlying photovoltaic, do excited-state species associated with coating layers contribute to photocurrent production via mechanisms involving dye-sensitization processes, and are relatively high or low loadings of catalytic sites advantageous. Herein, we highlight how optical and electrochemical characterization techniques can be coupled with structural information to address these questions. The experiments described in this work make use of a p-type gallium phosphide semiconductor that is interfaced with cobalt porphyrin hydrogen evolution reaction catalysts. However, the experimental techniques and discussions presented in this work can likely be applied to other materials and chemical transformations, providing a general yet useful strategy for better understanding the origin of photocurrents and fuel production activities in catalyst-modified semiconductor electrodes.
