Identification of catalytic sites in cobalt-nitrogen-carbon materials for the oxygen reduction reaction

Nitrogen-doped carbon materials with atomically dispersed iron or cobalt are promising for catalytic use. Here, the authors show that cobalt moieties have a higher redox potential, bind oxygen more weakly and are less active toward oxygen reduction than their iron counterpart, despite similar coordi...
