Catalytic four-electron reduction of O2 to water is one of the most extensively studied
electrochemical reactions due to O2 exceptional availability and high O2/H2O redox …

We describe as 'reversible'a bidirectional catalyst that allows a reaction to proceed at a
significant rate in response to even a small departure from equilibrium, resulting in fast and …

Efficient electrocatalytic energy conversion requires devices to function reversibly, that is, to
deliver a substantial current at a minimal overpotential. Redox-active films can effectively …

The enzyme FeFe-hydrogenase catalyzes H2 evolution and oxidation at an active site that
consists of a [4Fe-4S] cluster bridged to a [Fe2 (CO) 3 (CN) 2 (azadithiolate)] subsite …

Studies of molecular catalysts traditionally aim at understanding how a certain mechanism
allows the reaction to be fast. A distinct question, which has only recently received attention …

Hydrogenases display a wide range of catalytic rates and biases in reversible hydrogen gas
oxidation catalysis. The interactions of the iron–sulfur-containing catalytic site with the local …

Hydrogenases interconvert H2 and protons at high rates and with high energy efficiencies,
providing inspiration for the development of molecular catalysts. Studies designed to …

Conspectus Enzymes are the essential catalytic components of biology and adsorbing redox-
active enzymes on electrode surfaces enables the direct probing of their function. Through …

Some enzymes, including those that are involved in the activation of small molecules such
as H2 or CO2, can be wired to electrodes and function in either direction of the reaction …

Metal‐based formate dehydrogenases are molybdenum or tungsten‐dependent enzymes
that catalyze the interconversion between formate and CO2. According to the current …
