A composite of layered double hydroxides obtained through random costacking of layers from Mg–Al and Co–Al LDHs by delamination–restacking: Thermal decomposition and reconstruction behavior

Interstratification of trioctahedral and dioctahedral smectites through delamination and costacking

“…The thermal stability of the montmorillonite layers is increased as these layers are flanked by thermally more stable saponite layers. This behavior is similar to what we had earlier observed in the case of interstratified composites of two anionic clays [10].…”

“…Delamination, a process unique to layered solids [7,8], has much to offer in the preparation of nanocomposites as this process gives monolayer colloidal dispersion of layered solids which has the potential to blend layered solids with almost any type of guest species. We have recently shown the use of this method in the preparation of a number of composites such as layered solid-nanoparticle [9], MgAl LDH-CoAl LDH [10] and α-nickel hydroxide-α-cobalt hydroxide [11] composites.…”

Mixed oxides tuned with alkaline metals to improve glycerolysis for sustainable biodiesel production

“…The diffraction patterns of the rehydrated materials with the third metal incorporated showed partial recovery of the layer structure too. This could be due to the short contact time between the Mg-Al mixed oxide and the metal salt solution and because no washing process was performed to the samples [37]. Anyway, the purpose of rehydration with the cationic solution is to incorporate the third metal by impregnation rather than to rebuild the layer structure.…”

Effect of layered double hydroxides on ultraviolet aging resistance of SBS modified bitumen membrane

“…Layered double hydroxides (LDHs) are a family of important lamellar functional materials with supramolecular structures which have received a considerable interest in recent years due to their potential application [12,13] . LDHs possess a positively charged hydroxide basal layer, which are electrically balanced by the intercalation of anions in the interlayer space, and the interlayer anions can be replaced by other anions to form plenty of new functional materials [14,15] .…”
