Fig. 3. (a) XRD patterns of KCuHCF with different Rmix, where Rmix represents the molar mixing ratio of CuSO4 to K4[Fe(CN)6]. The notation ‘Si’ indicates the diffraction peak corresponding to silicon powder mixed with the samples for angle calibration. (b) FTIR spectra of CuHCF with the variation of Rmix.
