Photocatalytic O2 evolution from water over Zn–Cr layered double hydroxides intercalated with inorganic anions

Photocatalytic O-2 evolution from water over Zn-Cr layered double hydroxides intercalated with inorganic anions

Zn-Cr layered double hydroxides (LDHs) intercalated with inorganic anions (CO3, Cl, SO4 and NO3) were synthesized by the co-precipitation method and the anion exchange process. The photocatalytic activity of the LDHs was studied by O2 evolution from aqueous solution of AgNO3 as a sacrificial agent. All the prepared LDHs showed photocatalytic activity under either UV and/or visible light irradia...

Ab initio Investigation of Layered Double Hydroxides with Intercalated Herbicides

Layered double hydroxides (LDHs) or hydrotalcite-like compounds exist either as naturally occurring minerals or as synthesized materials by low-cost synthesis methods. LDHs consist of positively charged metal hydroxide layers having the composition [M1–x Mx(OH)2][Ax/m ·nH2O] where M and M are divalent and trivalent cations, respectively. The value of x is the molar fraction and can vary between...

Enhanced luminescence of europium-doped layered double hydroxides intercalated by sensitiser anions.

Four sensitising anions naphthalene-1,5-disulfonate (15-NDS), naphthalene-2,6-dicarboxylate (26-NDC), benzoate (BA) and terephthalate (TA) were intercalated into a Eu(3+)-doped Zn/Al layered double hydroxide. The carboxylate anions enhanced the red luminescence of Eu(3+) much more strongly than the sulfonate, in the descending order TA > 26-NDC > BA > 15-NDS.

Hybrid Inorganic–organic Composites of Layered Double Hydroxides Intercalated with Organic Acid Anions for the Uptake of Hazardous Substances from Aqueous Solution

Molecular dynamics study on structure evolution of monocarboxylic acid intercalated layered double hydroxides

Hydrotalcite derived materials are considered to be promising candidates for solid sorbents for carbon dioxide capture at intermediate temperatures (250–400 C). The recently developed organically intercalated layered double hydroxide (LDH) shows a great improvement in carbon dioxide adsorption capacity compared to alternative sorbents. However, the molecular-scale structure of this new class of...
