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. 1. EXAFS spectra and coordination structure of CA-CP. (a) Synthetic scheme for CA-CP. (b) K2 weighted Cu K edge Fourier-transform EXAFS spectra of CA-CP. Wavelet-transformed images of CA-CP (c), Cu foil (d) and CuO (e). (f) EXAFS fitting results of CA-CP at the R space. (g) Coordination mode between Cu atoms and alkynyls (left) and formation of Cu–Cu ’ladder’ (right) (yellow, Cu atoms; gray, C atoms). (h) Topology of CA-CP.
