Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 3. (a) XPS survey spectra of Cu/TiN NTs and Cu@TiO2 NWs without CuFo substrate and the control samples of TiN and CuFo substrate. (b-d) high-resolution XPS spectra of Cu 2p, Ti 2p and N 1 s, respectively. (e) Ti K-edge XANES and (f) Fourier transformed EXAFS of Ti foil, Cu/TiN NTs, and TiN. (g-i) Fourier transformed EXAFS of Ti foil, TiN, and Cu/TiN NTs.
