It was discovered that a single iron porphyrin, adsorbed at the surface of a graphite electrode, is a selective catalyst for the four-electron reduction of dioxygen to water, at pH 7. %G English %L hal-01469533 %U https://univ-rennes.hal.science/hal-01469533 %~ UNIV-BREST %~ UNIV-BOURGOGNE %~ CNRS %~ ICMUB %~ INC-CNRS %~ CEMCA-BREST %~ TEST-UNIV-RENNES %~ UNIV-RENNES %~ IBSAM %~ TEST2-HALCNRS
