a SIZ degradation in different systems. b Comparison of kinetics of catalytic systems. c Comparison of TOF values with state-of-the-art Fenton-like catalysts. d Time-dependent fluorescence intensity obtained from 1O2 captured by SOSG. e PMSO consumption and PMSO2 generation in catalytic systems. f Influence of SIZ on PMSO conversion. g Extracted ion chromatography of PMS16O16O and PMS16O18O generated from PMS16O in the D−FeN4−C/PMS system in H218O. h MS2 spectrum of PMS16O16O and PMS16O18O. i In situ Raman spectra. j Decline ratio of kobs in reusability tests for SIZ removal. k The kobs of reaction systems under different water substrates. l Removal ratio of multiple model pollutants in the D−FeN4−C/PMS system. Reaction condition: [pollutant]0 = 20 μM, [PMS]0 = 0.2 mM, [catalyst] = 0.05 g L−1, [TBA] = [MeOH] = [FFA] = [Carotene] = 0.1–500 mM (if any), initial pH = 6.5. Error bars are standard error values of three tests (n = 3). Source data are provided as a Source Data file.
