Abstract: The variations of Raman and optic absorption spectra of Co-Al layered double hydroxides (LDH) intercalated with nitrate and carbonate anions have been studied as a function of the Co2+/Al3+ ratio. It was revealed from the comparative analysis of the hydrogen bond frequencies in Raman spectra and the phonon repetition lines in optic absorption spectra that the increasing Co2+/Al3+ ratio results in an enhancement of the anion exchange ability in nitrate LDH and in a suppression of the ability in carbonate LDH.
