Mechanistic insights into the ORR/OER performance of FeN-doped fullerenes via Pt cluster size modulation

Among the Fe-N-doped fullerene-encapsulated Pt cluster models, Pt₁₀@FeN₄C₁₈₀ and Pt₁₁@FeN₄C₁₈₀ exhibit outstanding overpotential for the ORR (0.41 V) and OER (0.43 V), respectively, along with remarkable thermodynamic stability and resistance to poisoning.
