The activation and reduction of dioxygen (O2) by transition metal centers are key to a variety of biochemical and industrial processes. Efficient reduction of dioxygen to water is also important in the operation of fuel cells. These processes are typically proton-coupled electron transfer (PCET) reactions, requiring the coordinated movement of multiple protons and electrons. In biological systems, it is known that initial dioxygen bonding is facilitated by hydrogen bonding and proton delivery. This material is based upon work supported as part of the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the US Department of Energy, Office of Science, Office of Basic Energy Sciences.
