Figure 2. Atomic local structure and physicochemical properties of symmetric and asymmetric Fe SACs. a) WT-EXAFS profiles at Fe K-edge and b) EXAFS fitting curves (solid lines: experimental data; dots: fitted results) with coordination structure schematics (inset). c) Variation of bond length after asymmetric coordination. d) Normalized XANES spectra showing edge energy shifts versus reference materials. e) Correlation between charge density change (Δq) at Fe sites and dopant electronegativity (χ) with charge redistribution maps (inset: blue/yellow = electron depletion/accumulation). f) PDOS comparison highlighting the d-band center (dashed lines) shifting induced by asymmetric coordination. g) EIS of electrodes made from catalysts.
