We report here new approaches for the direct intercalation of layered double hydroxides (LDHs) from carbonate-LDHs by using various organic acids as proton sources de-carbonation.

Low-overpotential layered hydroxides (LDHs) with high theoretical capacity are promising electrodes for supercapaterry and oxygen evolution reaction; however, the low electronic conductivity insufficient active sites of bulk LDHs increase internal resistance reduce oxygen-production efficiency electrodes. Herein, we prepared a polyaniline-coated NiCo-layered double hydroxide intercalated MoO42?...

This work first transformed hazardous aluminum waste into low-cost MgAl−layered double hydroxide@ANA zeolite (LDHs@ANA) composite for dye wastewater adsorption, which was meaningful recovery and pollution control. Based on this strategy, the Al(OH)3 extracted from secondary dross (a in industry) used as an source to synthesize LDHs@ANA composite, had more excellent adsorption capacity methylene...

This review focuses on the extensive study of different layered double hydroxides (LDHs)nanostructures and also their biological and physicochemical (in vitro) properties to encapsulateand deliver drugs with a recognized pharmacokinetic profile in a sustained/modified manner forbetter remedial efficacy contrasted to the corresponding conventional treatments using different<br ...

The Layered Double Hydroxides are useful in many domains due their physical and chemical properties; in agriculture they are useful in order to obtain organic products. In this work, a study concerning the plant growth dynamics of corn plant during the LDH action is presented. To study the effect of LDHs on plant growth, we prepared MgAlLDH (Mg Al Layer Double Hydroxide), MgAlLDH+sodium paranit...

Highly ordered Cl(-) and SO4(2-)-intercalated layered double hydroxides (LDHs) of Cu(II) and Cr(III) are obtained when coprecipitation is carried out at low pH ~ 5 and elevated temperature (60-80 °C). Precipitation under other conditions results in the formation of a gel. The SO4(2-)-LDH exhibits weak reflections which could be indexed to the 100 and 101 planes of a supercell corresponding to a...

Interlayer structure, hydrogen-bond, hydration and swelling properties of glycine intercalated layered double hydroxides (LDHs-Gly) were investigated with molecular dynamics (MD) methods. The results show that the interlayer spacing dc increases as hydration level increases. The computed hydration energies reach the most negative values at low water contents and change rapidly over the range 1 ...

Layered double hydroxides (LDHs) are an ultraviolet-light (UV) resistant material. In this study, LDHs were used to modify bitumen. The optical and UV aging properties of LDHs modified bitumen were investigated. Firstly, the thin films of bitumen, with and without LDHs, were prepared. By using the UV-Vis spectrophotometer, absorbance, reflectance, and transmittance of bituminous thin film were ...

The immobilization of potassium sorbate, potassium aspartate and sorbic acid in layered double hydroxide under solid condition was examined. By simply mixing two solids, immobilization of sorbate and aspartate in the interlayer space of nitrate-type layered double hydroxide, so called intercalation reaction, was achieved, and the uptakes, that is, the amount of immobilized salts and the interla...

Double doped layered double hydroxide thin films were developed directly on the aluminum substrate in two steps: Initially cerium-based MgAl-layered (LDH) synthesized anodic surface via situ growth method, and then modified with stearate anions through an ion-exchange mechanism to achieve compact multifunctional protective films. The structural morphological characteristics of LDH investigated,...
