Hydrogen is an appealing goal for solar fuel production, but its efficient production requires both development of robust and renewable catalysts as well as efficient coupling to solar systems. Hydrogenases, the biological catalysts for reversible hydrogen oxidation and production, are unique enzymes that contain organometallic active sites consisting of iron alone or iron and nickel. Although a range of structural and functional mimics of hydrogenases have been reported, few have even a fraction of the catalytic activity of the enzymes. In this talk, I will describe recent progress in the use of peptides and redox non-innocent ligands to more accurately model the functional characteristics of hydrogenases. Particular attention will be paid to characterization of the electrocataltic properties of relevant complexes and performance in artificial photosynthetic systems.
