Identification of carbon-encapsulated iron nanoparticles as active species in non-precious metal oxygen reduction catalysts

Determining active species in non-precious metal catalysts for the oxygen reduction reaction remains a challenge due to catalyst heterogeneity. Here the authors perform gas-phase treatments on an iron-based catalyst to allow the identification of carbon-encapsulated iron nanoparticles as the active...
