a Schematic synthesis process for Fe-SAC-x catalyst with high Fe loading. b Fourier transformed infrared (FTIR) spectra of catalyst precursors (SOK: supramolecular organic skeleton). c Elemental mappings of Fe-SAC precursor obtained by the cascade anchoring strategy. d Nonlinear correlation between Fe-SAC loading and metal salt dosage. e Nonlinear correlation between SA wt% and OA dosage. f The metal loading of SAC prepared using different metal salts (nitrate, chloride, or sulfate) and metal types (transition, rare-earth, or noble metals). g–i FT of K-edge EXAFS spectra of Mn-SAC, Ag-SAC, and La-SAC, respectively.
