X-ray absorption analysis of Fe K-edge. a XANES spectra at the Fe k-edge of Fe2/mpg-C3N4, Fe2O3, and Fe foil. b Fourier transform (FT) at the Fe k-edge of Fe2/mpg-C3N4, Fe2O3, and Fe foil. c, d Corresponding fits of the EXAFS spectrum of Fe2/mpg-C3N4 at R space and k space, respectively. The inset of c is the schematic model of Fe2/mpg-C3N4 (Fe cyan, O red, N blue, and C gray)
