Figure 7. (A) Schematic illustration of the synthesis of Fe-N-G/CNT. (B-D) Geometry of the O2 adsorption mechanism on (B) Fe-N-CNT; (C) Fe-N-G; and (D) Fe-N-G/CNT and the corresponding O2 adsorption binding energies. (E) The three-dimensional charge density distribution of Fe-N-G/CNT absorbed O2. (F) LSV curves of the corresponding electrocatalysts in O2-saturated artificial seawater. (G) Discharge curves for different oxygen contents. (Reproduced with permission[99]. Copyright 2021, Wiley-VCH).
