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 …

Redox reactions play important roles in almost all biological processes, including
photosynthesis and respiration, which are two essential energy processes that sustain all life …

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 …

Molecular electrocatalysts can play an important role in energy storage and utilization
reactions needed for intermittent renewable energy sources. This manuscript describes …

If the atmosphere of the early Earth was hydrogen-rich, 1 it is reasonable to think that
hydrogenases, the enzymes enabling cells to use molecular hydrogen, were probably …

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 …

Background: Many microorganisms have the ability to either oxidize molecular hydrogen to
generate reducing power or to produce hydrogen in order to remove low-potential electrons …

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 …
