A specific demetalation of Fe–N4 catalytic sites in the micropores of NC_Ar + NH3 is at the origin of the initial activity loss of the highly active Fe/N/C catalyst used for the reduction of oxygen in PEM fuel cells

Is the rapid initial performance loss of Fe/N/C non precious metal catalysts due to micropore flooding?
