Figure 9. Schematic demonstration of the structure of Fe14MR (A) and FePc (B). CV curves for Fe-14MR/C (C) and FePc(D). (E) Relative concentration changing of Fe in Fe-14MR/C and FePc during CV cycling under N2 and O2. These figures are quoted with permission from Ohyama et al.[111]. (F) k3 -weighted FT-EXAFS spectra of P(AA-MA)(5-1)-Fe-N, PAA-Fe-N, and Fe foil samples. This figure is quoted with permission from Miao et al.[67]. (G) k3 -weighted FT-EXAFS spectra of sur-FeN4-HPC, FeN4-HPC, FePc, and Fe foil. This figure is quoted with permission from Chen et al.[68].
