By comparing the spectra obtained, the anionic species that are surface adsorbed to LDHs were proven to be distinguishable from those intercalated in the interlayer gallery. The IR spectra of the specimens were recorded by using four different techniques, which are different in their penetration depth (photoacoustic spectroscopy (PAS), attenuated total reflectance (ATR), diffuse reflectance IR spectroscopy (DRIFTS), and wide angle diffuse reflectance (WA-DRIFTS)). Depending on the initial interlayer ion, the organic molecules may end up between the layers and/or on the surface of the LDH. During the experimental work, first, CaAl-LDHs intercalated with nitrate/carbonate ions were transformed to d-gluconate- and benzoate-containing solids. In this work, a comparative study of various IR spectroscopic methods coupled with X-ray diffraction (XRD) is presented, which makes it possible to distinguish between the two possibilities. Also feel free to shoot a message with any questions.Guest molecules in layered double hydroxides (LDHs) may be located both on the surface and in the interlayer gallery.
