The synthesis of renewable fuels from abundant water or the greenhouse gas CO 2 is a major step toward creating sustainable and scalable energy storage technologies. In the last few decades, much attention has focused on the development of nonprecious metal-based catalysts and, in more recent years, their integration in solid-state support materials and devices that operate in water. This review surveys the literature on 3d metal-based molecular catalysts and focuses on their immobilization on heterogeneous solid-state supports for electro-, photo-, and photoelectrocatalytic synthesis of fuels in aqueous media. The first sections highlight benchmark homogeneous systems using proton and CO 2 reducing 3d transition metal catalysts as well as commonly employed methods for catalyst immobilization, including a discussion of supporting materials and anchoring groups. The subsequent sections elaborate on productive associations between molecular catalysts and a wide range of substrates based on carbon, quantum dots, metal oxide surfaces, and semiconductors. The molecule–material hybrid systems are organized as “dark” cathodes, colloidal photocatalysts, and photocathodes, and their figures of merit are discussed alongside system stability and catalyst integrity. The final section extends the scope of this review to prospects and challenges in targeting catalysis beyond “classical” H 2 evolution and CO 2 reduction to C 1 products, by summarizing cases for higher-value products from N 2 reduction, C x >1 products from CO 2 utilization, and other reductive organic transformations.

“…Immobilization of a S–M hybrid system in some special matrix by self‐assembly was demonstrated to be an effective strategy for efficient CST in addition to system stabilization. For example, co‐embedding of CdSe QDs and [FeFe] hydrogenase mimic into functionalized vesicles exhibited excellent HER activity . An interface‐directed assembly of [FeFe] hydrogenase mimics on CdSe QDs significantly improved the HER activity .…”

Converting sunlight to solar fuels by artificial photosynthesis is an innovative science and technology for renewable energy. Light harvesting, photogenerated charge separation and transfer (CST), and catalytic reactions are the three primary steps in the processes involved in the conversion of solar energy to chemical energy (SE‐CE). Among the processes, CST is the key “energy pump and delivery” step in determining the overall solar‐energy conversion efficiency. Efficient CST is always high priority in designing and assembling artificial photosynthesis systems for solar‐fuel production. This Review not only introduces the fundamental strategies for CST but also the combinatory application of these strategies to five types of the most‐investigated semiconductor‐based artificial photosynthesis systems: particulate, Z‐scheme, hybrid, photoelectrochemical, and photovoltaics‐assisted systems. We show that artificial photosynthesis systems with high SE‐CE efficiency can be rationally designed and constructed through combinatory application of these strategies, setting a promising blueprint for the future of solar fuels.

“…The surfactants used in these systems to encapsulate [FeFe]‐hydrogenase active‐site mimetics were sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), and dodecyltrimethylammonium bromide (DTAB) . In addition to the micellar systems, other biomimetic self‐assembling supporting systems such as phospholipid vesicle membranes were used for either embedding the components, for H 2 evolution catalysis, into the membranes or adsorbing the cluster to the membrane interface …”

Catalytic Metallopolymers from [2Fe‐2S] Clusters: Artificial Metalloenzymes for Hydrogen Production

Reviewed herein is the development of novel polymer‐supported [2Fe‐2S] catalyst systems for electrocatalytic and photocatalytic hydrogen evolution reactions. [FeFe] hydrogenases are the best known naturally occurring metalloenzymes for hydrogen generation, and small‐molecule, [2Fe‐2S]‐containing mimetics of the active site (H‐cluster) of these metalloenzymes have been synthesized for years. These small [2Fe‐2S] complexes have not yet reached the same capacity as that of enzymes for hydrogen production. Recently, modern polymer chemistry has been utilized to construct an outer coordination sphere around the [2Fe‐2S] clusters to provide site isolation, water solubility, and improved catalytic activity. In this review, the various macromolecular motifs and the catalytic properties of these polymer‐supported [2Fe‐2S] materials are surveyed. The most recent catalysts that incorporate a single [2Fe‐2S] complex, termed single‐site [2Fe‐2S] metallopolymers, exhibit superior activity for H2 production.
