Hydrotalcite-like compounds (HTlcs) containing Mg2+, Al3+, and Ce3+ in the hydroxide layer and with carbonate as charge-balancing anion have been prepared by a co-precipitation (at constant pH) method. The Al/Ce ratio in the final product depends on the concentration in the initial solution. The crystallinity of the layered materials decreases with the increase in cerium content, probably, due to the distortions introduced by the large difference in the ionic radii of the cations. All the synthesized materials were characterized by XRD, FT-IR spectroscopy and TG/DTA. The textural properties were determined from low-temperature nitrogen adsorption–desorption measurements.
Graphical abstractFrom the TG/DTA pattern of the various wt% of Ce containing Mg/Al HTlcs it is observed that the weight loss takes place in two different stages corresponding to two endotherms in the DTA pattern.Figure optionsDownload full-size imageDownload as PowerPoint slide
