Heterogeneous bimetallic catalysts have broad applications in industrial processes, but
achieving a fundamental understanding on the nature of the active sites in bimetallic …

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 …

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 …

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

Hydrogenases are abundant enzymes that catalyse the reversible interconversion of H2 into
protons and electrons at high rates. Those hydrogenases maintaining their activity in the …

Biological hydrogen production presents a possible avenue for the large scale sustainable
generation of hydrogen needed to fuel a future hydrogen economy. Amongst the possible …

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

Abstract Membrane-bound respiratory [NiFe]-hydrogenase (MBH), a H2-uptake enzyme
found in the periplasmic space of bacteria, catalyses the oxidation of dihydrogen: H2→ …

Ancient microbes invented biochemical mechanisms and assembled core metabolic
pathways on an anoxic Earth. Molecular oxygen appeared far later, forcing microbes to …
