Benzyltrimethylammonium hydroxide trihydrate containing hydroxide–water layers

Acta Crystallographica Section C Crystal Structure Communications, 2001
In the title compound, C(10)H(16)N(+) x OH(-) x 3H(2)O, two-dimensional bilayer-like arrays of organic cations and corrugated anionic hydroxide-water layers are stacked alternately along the c axis. All hydroxide and water H atoms are in ordered positions, giving rise to a network of hydrogen bonds [O...O 2.639 (2)--2.927 (2) A for water donors and O...

Intercalation of an oxalatooxoniobate complex into layered double hydroxide and layered zinc hydroxide nitrate

Journal of Colloid and Interface Science, 2009
A Zn/Al layered double hydroxide with molar ratio of 3 was prepared by coprecipitation in alkaline pH and used as a matrix to intercalate the ionic complex diaquadioxalatooxoniobate(V) (DDON), derived from NH(4)[NbO(C(2)O(4))(2)(H(2)O)(2)]2H(2)O.

Hollow nanoshell of layered double hydroxide

Chemical Communications, 2006
Hollow nanoshells of layered double hydroxide (LDH) have been fabricated using exfoliated LDH nanosheets as a shell building block and polystyrene beads as a sacrificial template.

A layered polymorph of rare earth hydroxides

Chemical Communications, 2013
A layered polymorph series of rare earth hydroxides has been developed by the conversion of RE2(OH)5Cl·mH2O to RE(OH)3·nH2O (RE = rare earths) with a typical layered structure with interlayer water molecules. A temperature-induced phase transition from the layered polymorph to its hexagonal form is completed at approximately 300 °C.

Layered double hydroxide hybrids with dicetylphosphate

Journal of Colloid and Interface Science, 2005
Dicetyl phosphate (DCP) ions incorporated into layered double hydroxide (LDH) clays to form a DCP/LDH hybrid were prepared and structurally characterized by X-ray diffraction analysis, scanning electron microscopy, thermogravimetry, and differential thermal analyses.

Dehydration of a layered double hydroxide—C2AH8

Thermochimica Acta, 2007
Thermal dehydration of dicalcium aluminate hydrate, C2AH8, has been investigated by simultaneous differential thermal and thermo gravimetric analysis (DTA/TGA), powder X-ray diffraction (XRD), temperature-dependent infrared spectroscopy (FT-IR), and BET method of surface area measurement.

Layered Double Hydroxide Stability. 1. Relative Stabilities of Layered Double Hydroxides and Their Simple Counterparts

Chemistry of Materials, 1999
Solutions containing di- and trivalent metal chlorides [M(II) = Mg2+, Zn2+, Co2+, Ni2+, Mn2+; M(III) = Al3+, Fe3+] were titrated with NaOH to yield hydrotalcite-like layered double hydroxides (LDH), [[M(II)]1-x[M(III)]x(OH)2][Cl]x yH2O, by way of M(III) hydroxide/hydrous oxide intermediates.

Selective Layer Reaction of Layer-by-Layer Assembled Layered Double-Hydroxide Nanocrystals

Journal of the American Chemical Society, 2007
The layer-by-layer assembly of layered double-hydroxide (LDH) nanocrystals was successfully accomplished by surface grafting using organic acids as coupling agents.
