    Theory suggests that many chemical reactions (not simply, as is often thought, redox reactions) might be catalysed by an applied electric field; experimental evidence for this is now provided from single-molecule studies of the formation of carbon–carbon bonds in a Diels–Alder reaction.

    A complex containing five atoms of iron is shown to be a highly efficient and robust water oxidation catalyst owing to the presence of redox flexibility, which enables charge accumulation and electron transfer, and the presence of adjacent active sites that enables intramolecular O–O bond formation.

    Electroreduction of carbon dioxide into useful fuels helps to reduce fossil-fuel consumption and carbon dioxide emissions, but activating carbon dioxide requires impractically high overpotentials; here a metal atomic layer combined with its native oxide that requires low overpotentials to reduce carbon dioxide is developed, adapted from an existing cobalt-based catalyst.
