Gases like H2, N2, CO2, and CO are increasingly recognized as critical feedstock in “green”
energy conversion and as sources of nitrogen and carbon for the agricultural and chemical …

While hydrogen plays an ever-increasing role in modern society, nature has utilized
hydrogen since a very long time as an energy carrier and storage molecule. Among the …

Infrared difference spectroscopy probes vibrational changes of proteins upon their
perturbation. Compared with other spectroscopic methods, it stands out by its sensitivity to …

Solar hydrogen production from water is a sustainable alternative to traditional hydrogen
production route using fossil fuels. However, there is still no existing large-scale solar …

Ever since the discovery of hydrogenases over 90 years ago (Stephenson and Stickland,
1931), their structure and mechanism of action have been intensively investigated. Of the …

Transition metal-driven small molecule activation is essential for the production of fuels and
chemicals or energy supply. The use of multimetallic catalysts, where two or more metal …

[FeFe]-hydrogenases are complex metalloenzymes, key to microbial energy metabolism in
numerous organisms. During anaerobic metabolism, they dissipate excess reducing …

Hydrogenases are redox enzymes that catalyze the conversion of protons and molecular
hydrogen (H2). Based on the composition of the active site cofactor, the monometallic [Fe] …

[FeFe] hydrogenases are extremely active H2-converting enzymes. Their mechanism
remains highly controversial, in particular, the nature of the one-electron and two-electron …
