Abstract

CaFe-layered double hydroxide (CaFe-LDH) was prepared by the co-precipitation technique and was treated mechanochemically in a mixer mill. The impacts of grinding frequency (3–21 Hz) and duration of milling (5–240 min) were mapped to learn about the deterioration steps of the layered structure. The possibility of structural reconstruction of the mechanochemically disordered chloride-containing LDH was tested in distilled water as well as in nitrate-containing aqueous solution. The main methods to follow the deformation and the rearrangement process were X-ray diffractometry and infrared spectroscopy, but electron microscopy techniques and thermal analysis were also applied to better understand and visualize the disruption and reconstitution of the LDH framework.
