The synthesis of the material was accomplished through a nanocasting approach using pyrrole as the nitrogen and carbon source, and iron chloride as the iron dopant. The Fe–N–C thus-synthesized consists of small nanoparticles with a diameter of ∼240 nm and a pompom-like morphology. They exhibit a relatively high specific surface area combined with a very accessible porosity and a high nitrogen (∼11 wt %) and iron (∼5 wt %) content. With respect to electrocatalytic activity, in basic electrolyte the Fe–N-doped carbon nanopompoms exhibited high onset (0.94 V) and half-wave potentials (0.82 V), and a large kinetic current density (19 mA cm–2), higher than commercial platinum catalysts. The electrocatalysts were also tested in acid electrolyte, giving an onset potential of 0.75 V and a peroxide yield lower than 10% over a wide range of potentials. Furthermore, the newly developed carbon nanostructures exhibit excellent durability, better than commercially available platinum in both media. The excellent electrocatalytic activity is attributed to a combination of a high specific surface area with very accessible porosity and the presence of numerous active centers (i.e., iron coordinated to nitrogen and nitrogen functional groups).This research work was supported by the FICYT Regional Project (GRUPIN14-102), the Spanish MINECO-FEDER (CTQ2015-63552-R) and CSIC (201660I027).Peer reviewedAmerican Chemical SocietyMinisterio de Economía y Competitividad (España)Principado de AsturiasÁlvarez Ferrero, Guillermo [0000-0001-8606-781X]Díez Nogués, Noel [0000-0002-6072-8947]Sevilla Solís, Marta [0000-0002-2471-2403]Fuertes Arias, Antonio Benito [0000-0002-5931-1669]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201820182018info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/173180reponame:DIGITAL.CSIC.
