ABSTRACT The research on structural and functional biomimics of the active site of [FeFe]-hydrogenases is in an attempt to elucidate the mechanisms of H(2)-evolution and uptake at the [FeFe]-hydrogenase active site, and to learn from Nature how to create highly efficient H(2)-production catalyst systems. Undoubtedly, it is a challenging, arduous, and long-term work. In this perspective, the progresses in approaches to photochemical H(2) production using mimics of the [FeFe]-hydrogenase active site as catalysts in the last three years are reviewed, with emphasis on adjustment of the redox potentials and hydrophilicity of the [FeFe]-hydrogenase active site mimics to make them efficient catalysts for H(2) production. With gradually increasing understanding of the chemistry of the [FeFe]-hydrogenases and their mimics, more bio-inspired proton reduction catalysts with significantly improved efficiency of H(2) production will be realized in the future.

    ABSTRACT: This perspective article reviews the recent important progress in electrocatalytic hydrogen production catalyzed by earth-abundant metal complexes. The catalysts are divided into two categories depending on the media used in the hydrogen-evolving reactions, with an emphasis on the types of acids employed. The catalysts used in the first category, which work in organic solutions, include nickel and cobalt complexes with base-containing diphosphine ligands, cobaloximes, cobalt tetrapyridine complexs, and [NiFe]- and [FeFe]-hydrogenase mimics. Molybdenum and cobalt pentapyridine complexes, as well as the cobalt bis(iminopyridine) complex reported very recently, are the most important examples of catalysts used in the second category, which work in aqueous solutions. The advantages and disadvantages of the different types of catalysts are discussed and the hydrogen-evolving mechanisms for the well-studied catalysts are illustrated. In addition, several molecular catalyst-modified electrodes for hydrogen production are described.

    ABSTRACT: The photocatalytic hydrogen evolution inspired by the highly evolved, finely tuned molecular photo-synthetic systems in nature represents an important process in sustainable solar energy conversion for the near future. By incorporating a phosphine donor within a thiosemicarbazone moiety, a new proton reduction catalyst Ni−thioP, featuring NiH interactions was synthesized and structurally characterized. Single crystal structure analysis revealed that the C–S, C–N and N–N bond lengths were all within the normal range of the single and double bonds, suggesting the extensive electron delocalization over the ligand skeleton. The presence of NiH interactions relative to the amide group coupled with the easy proton migration pathway involving thioamide/thiolate exchange suggested that the thiosemicarbazone complexes could serve as promising candidates for proton reduction. Luminescence titrations exhibited that Ni−thioP served as efficient luminescent quenchers for the photosensitizer Fl, providing the possibilities for the excited state of Fl to activate these catalysts for proton reduction. The direct generation of hydrogen was achieved by carrying out the photolysis of a solution containing fluorescein as the photosensitizer, and triethylamine as the sacrificial and the redox catalysts. Ni−thioP exhibited high activity with a turnover number (TON) of 8000 moles of H2 per mole of the catalyst after 24 hours and an initial TOF larger than 500 moles of H2 per catalyst per hour. To further investigate the potential mechanism for proton reduction, calculations were also performed using density functional theory.

    ABSTRACT: The development of energy-efficient, cost-effective and durable photocatalytic systems for water splitting is one of the scientific problems that must be solved before the successful transformation from a fossil fuel-based economy to a solar fuel-based economy can be realized. Conventional photocatalytic systems are generally divided into heterogeneous systems of semiconductors, usually modified by noble metals or inorganic cocatalysts, and homogeneous systems comprised of molecular catalysts and organic or organometallic chromophores. In recent years, some hybrid photocatalytic systems were reported to be highly active and robust for photoinduced H2 production, indicating that the integration of semiconducting materials with proper molecular catalysts is an effective strategy for constructing efficient photocatalytic systems for water splitting. This review will focus on hybrid photocatalytic systems, developed in the past three years, in which proton reduction molecular catalysts incorporate either semiconducting materials or inorganic, metal-organic, and other polymeric nanomaterials for photochemical H2 generation from water. In the last section of the review, problems existing in the current hybrid photocatalytic systems are discussed; future challenges and developments are envisaged.
