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 …

Hydrogen is an important industrial material and ideal secondary energy. It is widely used in
petrochemical, electronics, metallurgy, food processing, fine organic synthesis, and clean …

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 …

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] …

Growing concerns over greenhouse gas emissions and energy insecurity caused by the
depletion of conventional fuels have led to a search for sustainable fuel alternatives. As an …

[FeFe] hydrogenases, metalloenzymes catalyzing proton/dihydrogen interconversion, have
attracted intense attention due to their remarkable catalytic properties and (bio-) …

Enzymes catalyse target reactions under mild conditions with high efficiency, as well as
excellent regional-, stereo-, and enantiomeric selectivity. Photocatalysis utilises sustainable …

Conspectus Hydrogenases are metalloenzymes that catalyze proton reduction and H2
oxidation with outstanding efficiency. They are model systems for bioinorganic chemistry …

[FeFe]-hydrogenases are known for their high rates of hydrogen turnover, and are
