a In-situ Raman spectra to investigate the formation of δ(H···Cl–O) and the generation process of ≡FeIV = O with FeS2 and ClO2−. b EPR spectra to determine ClO2 generated by FeS2 and ClO2– without any trapping agent. c UV–vis spectra to detect the transformation from ClO2– (262 nm) to ClO2 (350 nm). d XPS spectra of Cl 2p scan on R-FeS2-ClO2 and R-FeS2. e Raman spectra of the Fe-Cl bond and Fe-S bond signals in R-FeS2-ClO2, R-FeS2, original FeS2 and FeCl3. EXAFS spectra and corresponding fitting lines of (f) R-FeS2-ClO2 and g R-FeS2. h Illustration of the transformation process from Fe-S to Fe-Cl bond for PA-≡FeIV = O synthesis with ClO2 as the inducer. 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. 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).
