MXene interlayer–confined CuFeO<sub>2</sub> electroactive membrane for efficient activation of peroxymonosulfate and continuous-flow degradation of 17α-ethynylestradiol

Figure 4. (A) Scavenging of reactive species during EE2 degradation by CuFeO₂–MX; EPR spectra of (B) •O₂^- and (C) h⁺; (D) Concentrations of h⁺ and •O₂^- during the degradation process; (E) Possible intermediates and reaction pathways during EE2 degradation by CuFeO₂–MX. Data are presented as mean ± SD (n = 3). EE2: 17α-Ethynylestradiol; CuFeO₂–MX: CuFeO₂–MXene; EPR: electron paramagnetic resonance; SD: standard deviation
