Figure 3. (A) In-situ FT-IR spectra of ethanol adsorption on Ni-NiAlZr-LDO at 120 °C under ambient atmosphere; (B) Normalized intensity of the band at 1,576 cm^-1 as a function of adsorption time ethanol adsorption on varied Ni-LDO at 120 °C; (C) Normalized intensity of the band at 1,576 cm^-1 as a function of desorption time detected in ethanol desorption on varied Ni-LDO at 120 °C. FT-IR: Fourier transform infrared; LDO: layered double oxides.
