Activity, Performance, and Durability for the Reduction of Oxygen in PEM Fuel Cells, of Fe/N/C Elect
Electrochimica Acta Volume: 159 Pages: 184-197 Published: 2015 Fe/N/C type catalysts have been produced by ballmilling ZIF-8 (a metal-organic-framework) and a chloroiron-tetramethoxyporphyrin (ClFeTMPP). The resulting material was first pyrolyzed in Ar at temperatures ranging from 850 to 1150 °C, then in NH3 at 950 °C in order to produce two series of catalysts: the Ar and the Ar + NH3 ones. They were labeled NC Por_x-T Ar or NC Por_x-T Ar + NH3, where x is the nominal Fe loa
