MOF-derived dual metal (Fe, Ni) –nitrogen–doped carbon for synergistically enhanced oxygen reduction reaction

Fe-N-C materials have been shown as promising non-precious electrocatalysts for oxygen reduction reaction (ORR), yet the activity as well as the durability in acidic electrolytes is still far from satisfactory. Herein, a dual metal (Fe, Ni)-nitrogen-doped carbon (FeNi-NC) was prepared by pyrolysis of Fe, Ni co-doped ZIF-8. The FeNi0.25-NC catalyst exhibits a comparable activity for the ORR to the commercial Pt/C catalyst, with the half-wave...
