title = "Defective nitrogen-doped graphene foam: Clarifying the role of nitrogen in non-precious ORR catalysts",
abstract = "Iron-free, nitrogen-doped graphene foam is presented as a model electrocatalyst system for studying the role of nitrogen in the oxygen reduction reaction in non-precious Fe/N/C-based electrocatalysts. Due to the large surface area and high porosity, these electrocatalysts display high activity in rotating ring-disk electrode voltammetry measurements. The electron transfer number is as high as 3.6, despite the metal-free nature of this electrocatalyst. The sample with the highest activity has a significantly larger proportion of tertiary/graphite-like nitrogen, and therefore this is proposed as a 4-electron oxygen reduction active site in acid environment.",
