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 …

Two decades ago, theoretical model calculations played a truly minor role in understanding
mechanisms of redox-active metalloenzymes. The methods available to treat transition …

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

Formation of stable iron hydrides on more nucleophilic (electron-rich) metal centers than
those found in hydrogenases with CO ligands would inhibit or at least slow down function …

Many microorganisms, such as methanogenic, acetogenic, nitrogen-fixing, photosynthetic,
or sulfate-reducing bacteria, metabolize hydrogen.[1, 2a] Hydrogen activation is mediated by …

Fe-only hydrogenases, as well as their NiFe counterparts, display unusual intrinsic high-
frequency IR bands that have been assigned to CO and CN-ligation to iron in their active …

Stoichiometric and catalytic transition-metal reactions have attracted great interest for their
many applications in industrial and synthetic processes. Transition-metal reactions are …

Fossil fuels like coal, oil, and natural gases are not renewable on a human time scale and
when combusted they pollute the earth's atmosphere with carbon dioxide. The latter is …
