Long‐Term Structural Evolution of an Intercalated Layered Semiconductor

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...

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...

Pamoate intercalated Zn-Al layered double hydroxide for the formation of layered organic-inorganic intercalate

A layered organic-inorganic intercalate was prepared by the self-assembly technique using pamoate (PA) as an organic guest in the Zn-Al layered double hydroxide inorganic host (ZAPAN). Various concentrations of PA, ranging from 0.01 to 0.04 M, were used to prepare the intercalated compound with a constant 4:1 ratio of Zn:Al in the mother liquor. The concentration of PA of 0.02 M at pH 7 was fou...
