Hydrogen-Producing Catalysts Based on Ferredoxin Scaffolds.

ABSTRACT: Current attempts to transform our fossil fuel-based society into a sustainable one involve learning from and employing the biochemistry of nature. The process of photosynthesis is exemplary for utilizing sunlight as a regenerative energy source. Enzymes like hydrogenases, which reduce protons to molecular hydrogen (H₂) under ambient conditions, are model biocatalysts for generating sustainable, clean fuels. In green algae, photosynthesis and hydrogenases are coupled through ferredoxin, a small electron transfer protein. Here, it is shown that several plant-type ferredoxins can interact with a chemically synthesized active site cofactor analog of [FeFe]-hydrogenases in a way that allows comparably high H₂ evolution rates.
