Figure 8. Catalytic performance of the FeC4 moiety towards oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in an acidic medium. (A) Reaction pathways of ORR and OER catalyzed by the FeC4 moiety, where the most stable adsorption configurations of O, OH, OOH, and 2OH are given. Gibbs free energy diagrams of (B) ORR and (C) OER.
