Fe-N-C catalysts are prepared from FePc with different heat treatments
The best Fe-N-C catalyst is prepared through pyrolysis at 850 °C
Different porous silica are used as template to modify the morphology and porosity
ORR electroactivity in acidic solution is determined with RRDE and GDE apparatuses
The best catalyst Fe-N-C/850_mSiO2 presents the highest microporosity
