“…Layered double hydroxides (LDHs), as a class of synthetic two‐dimensional nanostructured anionic clays, due to high surface area and good anion‐exchange properties, can act as hosts with a two‐dimensional expandable interlayer space for intercalation of guest species or to bind such species to their surface . The intercalated solids not only prevent aggregation and deactivation of the catalytically active guest molecules but mostly promote a special environment for the reaction between the active catalytic species and the substrate and therefore increase chemical and thermal stability of active molecules during catalytic processes . In addition, recovery and reusability of the intercalated materials are more feasible.…”

The preparation and characterization are presented of a new catalytic material comprising Mg–Al layered double hydroxide and intercalated manganese(III) 5,10,15,20‐tetrakis(4‐benzoate)porphyrinacetate. Characterization was realized via various techniques. The prepared composite exhibited excellent catalytic activity in the selective epoxidation of various olefins with tetra‐n‐butylammonium hydrogen monopersulfate as an oxidant under mild reaction conditions. Furthermore, the catalytic system could be reused nine times without significant reduction in conversion percentage and any special care or additional treatment of the catalyst.

“…Furthermore, their bending vibrations have appeared at 1614 cm − 1 [41]. The strong absorption peak at 1376 cm − 1 is related to the v 3 vibration mode of interlayer nitrate anions and the v 1 and v 2 vibrations of nitrate ions are also weakly noticeable at 1050 and 825 cm − 1 [42].…”

Designing e cient membranes for desalination to help reduce the water shortage crisis has been the subject of various studies. In this study, rst, CuAl LDH nanosheets were prepared and the surface of some thin-lm composite (TFC) membranes was modi ed by them. Afterward, the novel heterostructure nanocomposite consisting of CuAl LDH and WS 2 nanosheets was synthesized by hydrothermal method, and a new kind of thin-lm nanocomposite (TFN) membranes were made using them. All the obtained membranes performance was studied in the forward osmosis (FO) process. The effects of the prepared compounds on the morphology, chemical structure, hydrophilicity, and topology of the polyamide (PA) active layer were evaluated by scanning electron microscopy (SEM), FT-IR spectroscopy, energy-dispersive X-ray (EDX), powder x-ray diffraction (XRD), water contact angle (WCA) goniometer and atomic force microscope (AFM) analysis. Finally, by comparing the results for both types of modi ed membranes, the membrane containing 0.025 wt% of the nanocomposite modi er showed the highest water ux (29.30 LMH) and selectivity (0.38 g/L) that was chosen as the optimal membrane. Also, the anti-fouling properties of this membrane were studied and the obtained results showed an increase in the fouling resistance compared to the membrane without ller. HighlightsFO membranes were modi ed separately using CuAl LDH and WS 2 /CuAl LDH nanosheets.The incorporated nanosheets provided a hydrophile and smooth surface for the polyamide active layer.WS 2 /CuAl LDH nanocomposite modi ed membranes exhibited better selectivity than TFC and CuAl LDH modi ed membranes.TFN-WL 2 membranes as the optimal membrane showed higher anti-fouling properties compared to the TFC membrane.

Oxido-peroxido W(VI)-histidine-MgAl-layered double hydroxide composite was prepared by using MgAl-layered double hydroxide as a host and oxidoperoxido W(VI)-histidine complex as a guest. The composite was characterized by XRD, IR, EDX,SEM and TEM techniques. This composite is tested for catalytic selective sulfoxidation reactions using hydrogen peroxide as oxidant showing good to moderate conversion along with high selectivity.
