In this study, by using first principles simulation techniques, we explored the basal spacings, interlayer structures, and dynamics of arsenite and arsenate intercalated Layered double hydroxides (LDHs). Our results confirm that the basal spacings of NO3-LDHs increase with layer charge densities. It is found that Arsenic (As) species can enter the gallery spaces of LDHs with a Mg/Al ratio of 2:...

(1) Background: In time, stone monuments suffer a process of aging and loss aesthetic mechanical properties. order to restore stop the their properties, various treatments are used, in this context, new class discovered materials with interesting properties layered double hydroxides, or LDHs. (2) Methods: The LDHs, prepared by coprecipitation method, were characterized structure X-ray diffracti...

Unstable oxidation state +3 of nickel can be stabilized in the structure layered double hydroxides, resulting crystallinity and properties being dependent on synthesis method. Three different wet chemical methods (co-precipitation at variable pH, co-precipitation followed by hydrothermal treatment, with microwave treatment) were used to synthesize Mg/Ni–Al hydroxides containing triply charged c...

Layered Double Hydroxides (LDHs)-based drug delivery systems have, for many years, shown great promises for the delivery of chemical therapeutics and bioactive molecules to mammalian cells in vitro and in vivo. This system offers high efficiency and drug loading density, as well as excellent protection of loaded molecules from undesired degradation. Toxicological studies have also found LDHs to...

Layered double hydroxides (LDHs) and rare earth elements (REEs) have both attracted extensive attention because of their structures and properties. The layered structure of LDHs makes it possible for many functional ions to be incorporated and the uniform dispersion of metal organic anions in interlayer galleries or metal cations in layers extends the applications of layered materials to a wide...

Trace metals (e.g. Ni, Zn) leached from industrial and agricultural processes are often simultaneously present in contaminated soils and sediments. Their mobility, bioavailability, and ecotoxicity are affected by sorption and cosorption at mineral/solution interfaces. Cosorption of trace metals has been investigated at the macroscopic level, but there is not a clear understanding of the molecul...

The photocatalytic conversion of CO2 into useful chemical compounds in water without using organic sacrificial reagents is a promising method to overcome environmental and energy problems. Various synthesized layered double hydroxides (LDHs) are capable of reducing CO2 to CO in an aqueous solution under UV light irradiation. However, it is difficult to oxidize H2O to O2 in a photocatalytic syst...
