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 …

The modularity and synthetic flexibility of metal–organic frameworks (MOFs) have provoked
analogies with enzymes, and even the term MOFzymes has been coined. In this review, we …

Reduction of oxides and oxoanions of carbon and nitrogen are of great contemporary
importance as they are crucial for a sustainable environment. Substantial research has been …

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 …

Electron bifurcation is a fundamental energy coupling mechanism widespread in
microorganisms that thrive under anoxic conditions. These organisms employ hydrogen to …

Whole‐cell inorganic‐biohybrid systems, integrating inorganic photosensitizers with intact
living cells, have shown great potential for solar hydrogen production. However, the typical …

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

Studies of molecular catalysts traditionally aim at understanding how a certain mechanism
allows the reaction to be fast. A distinct question, which has only recently received attention …

As paradigms for proton-coupled electron transfer in enzymes and benchmarks for a fully
renewable H2 technology,[FeFe]-hydrogenases behave as highly reversible electrocatalysts …
