a Electrostatic potential in Fe, O, S, and Cl atoms in PA-≡FeIV = O and PS-≡FeIV = O. The blue ball refers to the Fe atom, the yellow ball refers to the S atom, the green ball refers to the Cl atom and the red ball refers to the O atom. b Fe K-edge XANES spectra of R-FeS2-ClO2, R-FeS2, original FeS2 and FeCl3. c XPS spectra on Fe 2p scan of R-FeS2-ClO2 and R-FeS2. d Mössbauer spectra to differentiate the electronic structure of PA-≡FeIV = O and PS-≡FeIV = O. e Schematic illustration of the work functions of PA-≡FeIV = O and PS-≡FeIV = O. Ef represents the Fermi level. Experiment conditions: [FeS2]0 = 1.0 g/L (if not specified), [ClO2–]0 = 1.0 mmol/L (if not specified), [Na2S2O3]0 = 1.0 mmol/L (if not specified).
