Degradation and regeneration of Fe–N(x) active sites for the oxygen reduction reaction: the role of surface oxidation, Fe demetallation and local carbon microporosity

The severe degradation of Fe–N–C electrocatalysts during a long-term oxygen reduction reaction (ORR) has become a major obstacle for application in proton-exchange membrane fuel cells. Understanding the degradation mechanism and regeneration of aged Fe–N–C catalysts would be of particular interest f...
