Silica-based mixed oxide pillared layered α-zirconium phosphates

Microporous and Mesoporous Materials, 2002
Abstract Mixed Al–Si, Cr–Si and Fe–Si oxide pillared α-zirconium phosphates have been prepared by intercalation of binary oxide oligomers into colloidal α-zirconium phosphate (ZrP) at reflux temperature. Most of the pillared materials with less than 10 wt.% of trivalent metal oxide are thermally stable on calcination at 773 K and maintain free ...

Hydrothermal Synthesis of Alumina Pillared Layered α- Zirconium Phosphate

MRS Proceedings, 1994
AbstractA new strategy to prepare alumina pillared α-zirconium phosphate with enhanced surface area and narrow pore size distribution is reported. The required precursor, a highly expanded single phase intercalate, is obtained in two steps. In the first one, the oligomeric solution of aluminium, prepared by dissolving aluminium in a solution of A1C13at

Chromatographic behaviour of inorganic ions on crystalline titanium phosphate or zirconium phosphate thin layers

Journal of Chromatography A, 1967
Abstract The chromatographic behaviour of alkali metal ions, alkaline earths and Tl(I) on crystalline and amorphous zirconium phosphate and titanium phosphate thin layers has been examined. Large differences in the ion exchange properties of amorphous and crystalline materials were found.

Hydrothermal synthesis of layered zirconium phosphates and their intercalation properties

Environmental Technology
Layered inorganic materials are widely used as fillers in nanocomposites due to their unique properties such as mechanical performance, thermal properties, flame resistance, barrier properties, corrosion resistance, catalytic activity, and multifunctionality.

Polyaniline/Layered Zirconium Phosphate Nanocomposites: Secondary-Like Doped Polyaniline Obtained by the Layer-by-Layer Technique

Journal of Nanoscience and Nanotechnology, 2008
In the present work, nanocomposites of polyaniline (PANI) and layered α-Zr(HPO4)2˙H2O (α-ZrP) were prepared using two different approaches: (i) the in situ aniline polymerization in the presence of the layered inorganic material and (ii) the layer-by-layer (LBL) assembly using an aqueous solution of the polycation emeraldine salt (ES-PANI) and a ...

Exchange of iron ions into layers of α-zirconium phosphate

Solid State Ionics, 2001
Abstract Exchange of Fe 3+ and Fe 2+ ions into layers of α-zirconium phosphate is achieved in aqueous media by using monosodium and/or ethanolic forms of the host precursor. The products obtained are characterized by chemical analysis, X-ray powder diffraction and Mossbauer spectroscopy.

Layered and pillared zirconium phosphate-phosphonates and their inclusion chemistry

Supramolecular Chemistry, 1995
Abstract After a brief account on previous results obtained in this Laboratory in the field of layered and pillared α- and γ-zirconium phosphonates, the perspectives for a development of a “molecular recognition” in porous and in layered solids are examined.

Silylation of layered zirconium hydroxy phosphate and its porous properties

Journal of Materials Science, 2007
Silylation of layered zirconium hydroxy phosphate was carried out and its porous properties were examined. The novel layered hydroxy phosphate was protonated and intercalated by using octylamine to expand the interlayer space. Then, dimethyldichlorosilane, dichloromethylvinylsilane or 1,2-bisdimethylchlorosilylethane were used to silylate the ...
