Nanoparticle characterization. (A) Comparison between the FTIR spectra of the stretching vibration of the cyano group in the Nihcf nanoparticles (solid line) and the surfactant CTAFeII (dashed line). (B) XRD patterns of the mixture Nihcf-CTAB; Nihcf nanoparticles are subtracted from the mixture pattern, and the peaks are assigned to CTAB diffraction according to Wong-Ng et al. [51].
