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 …

Density functional theory (DFT) was employed to investigate the behavior of a series of
catalysts used in the hydrogen evolution reaction (HER, 2H++ 2e-→ H2). The kinetics of the …

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 …

Hydrogen production through water splitting is one of the most promising solutions for the
storage of renewable energy.[NiFe] hydrogenases are organometallic enzymes containing …

Prospects in light‐driven water activation have prompted rapid progress in hydrogenation
reactions. We describe a Ni2+− N4 site built on carbon nitride for catalyzed …

Hydrogenase proteins catalyze the reversible conversion of molecular hydrogen to protons
and electrons. The most abundant hydrogenases contain a [NiFe] active site; these proteins …
