Fig. 3. (a) Normalized Fe K-edge XANES spectra of as-prepared catalysts and reference samples (i.e., Fe foil, FeO, Fe2O3, and Fe3O4) and (b) the corresponding Fe composition ratio based on LCF-XANES fitting. (c) k3-weighted Fourier transformed EXAFS spectra of the as-prepared catalysts and reference samples (i.e., Fe foil, FeS, and Fe2O3). (d) Schematic diagram of the structural changes with temperature-dependent.
Fig. 6. (a) Fe compositions based on LCF-XANES fitting and (b) C, N, Fe, and S composition ratios based on XPS fitting of used BC-800. (c) Variation in Fe2+, total iron, and PMS concentrations in the solution. (d) Photographic image of the continuous flow device. (e) 4-CP removal efficiency over 24 h using the membrane system experimental setup.
