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 …

Hydrogenase enzymes efficiently process H2 and protons at organometallic FeFe, NiFe, or
Fe active sites. Synthetic modeling of the many H2ase states has provided insight into …

The reaction takes place at a specialized metal center that dramatically increases the acidity
of H2 and leads to a heterolytic splitting of the molecule which is strongly accelerated by the …

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 …

Over the last 15 years, a plethora of research has provided major insights into the structure
and function of hydrogenase enzymes. This has led to the important development of …

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 …

This article sets out to review the chemistry relating to the synthesis of structural and
functional analogues of the three classes of hydrogenases. This chemistry has grown …

The enzyme hydrogenase reversibly converts dihydrogen to protons and electrons at a
metal catalyst. The location of the abundant hydrogens is of key importance for …

The utilization of hydrogen by micro-organisms as a source of reducing power or of protons
as final electron acceptors is mediated by metalloenzymes called hydrogenases. The need …

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 …
