Enzymatic catalysis has fueled considerable interest from chemists due to its high efficiency
and selectivity. However, the structural complexity and vulnerability hamper the application …

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 …

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 …

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 …

Hydrogenases are the most active molecular catalysts for hydrogen production and uptake,,
and could therefore facilitate the development of new types of fuel cell,,. In [FeFe] …

Abstract The [FeFe]-and [NiFe]-hydrogenases catalyze the formal interconversion between
hydrogen and protons and electrons, possess characteristic non-protein ligands at their …

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 …

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 …
