Modulating electronic structure of Co-N<sub>5</sub>S<sub>1</sub> sites in Co single atom catalysts via phosphorus incorporation and nanoclusters to promote oxygen electrocatalytic activity

Figure 5. (A) Schematic presentation of side view and top view atomic model of Co_SA+NC/NPSC; (B) Pathways for the Co_SA+NC/NPSC at 0 V with four oxygen intermediate models inserted; (C) ORR and (D) OER free energy ladder diagrams at 1.23 V vs. RHE; (E) The theoretical d band center and (F) differential charge density of Co_SA+NC/SC, Co_SA+NC/NSC and Co_SA+NC/NPSC (yellow and cyan represented the electron accumulation and electron depletion). ORR: Oxygen reduction reaction; OER: oxygen evolution reaction; RHE: reversible hydrogen electrode.
