The chemical structure of samples was complementary investigated by Fourier Transform Infra-Red (FTIR) spectroscopy in attenuated total reflectance (ATR) mode. The FTIR-ATR spectra were collected in the fingerprint 1400–550 cm−1 wave numbers range using a PerkinElmer BX Spectrum II apparatus (PerkinElmer Corporation, Waltham, MA, USA), equipped with diamond-zinc selenide Pike MIRacle (PIKE Technologies, Madison, WI, USA) ATR crystal attachment (with a diameter of 1.8 mm). The spectra were acquired at a resolution of 4 cm−1. A total of 32 scans were recorded for each sample and the resulting interferogram was averaged.
