(A) Schematic illustration for the synthesis routes of CMS-rGO NSs. (B) Fourier transforms of k³-weighted EXAFS oscillations obtained at the Mo K-edge of MS, MS-rGO NSs and CMS-rGO NSs and EXAFS curve fittings of CMS-rGO NSs on [χ(R)] and Re[χR)]. (C) Decomposition curves of different dye pollutants in CMS-rGO NSs suspensions with H₂O₂ and kinetic curves for RhB degradation in various suspensions with H₂O₂. (D) BMPO spin-trapping EPR spectra for HO₂^•/O₂^•− and ^•OH in the CMS-rGO NSs suspensions in the absence/presence of H₂O₂ with/without dye pollutants. (E) Schematic for the novel Fenton-like reaction process in CMS-rGO NSs systems under Catalyst+H₂O/O₂+H₂O₂+Dye conditions. Adapted with permission from ref. [58], Copyright©2019, Elsevier.
