Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 2. (a) Ti 2p XPS spectra, (b) EPR spectra, (c) O 1s XPS spectra, and (d) C 1s XPS spectra for pure TiO2 and 18%C,N/TiO2. (e) N 1s XPS spectra of 18%C,N/TiO2. (f) The XANES spectra (inset is the magnified image) and (g) Fourier-transformed Ti K-side EXAFS spectra of Ti foil, pure TiO2, 18%C,N/TiO2, TiC, and TiN. (h) The wavelet transforms for the k3-weighted EXAFS signals of Ti foil, pure TiO2, and 18%C,N/TiO2 samples.
