Oxide layers with titanium and zirconium phosphates

Russian Journal of Inorganic Chemistry, 2008
Oxide-phosphate layers 20 to 150 μm thick were obtained on titanium by plasma electrolytic deposition in individual and mixed aqueous electrolytes with polyphosphate complexes of zirconium(IV), barium(II), and copper(II). Formation features, thickness, elemental and phase compositions, and surface morphology of the films are presented. Depending on the

Ionothermal Synthesis and Structure of a New Layered Zirconium Phosphate

Inorganic Chemistry, 2015
A new layered zirconium phosphate material has been synthesized ionothermally using N-ethylpyridinium (Epy) bromide as both the solvent and the template, and its structure has been solved from synchrotron X-ray powder diffraction data using the charge-flipping routine implemented in Superflip.

Amino Acid Derivatives of Layered Zirconium Phosphates – α-Zirconium L-(+)-Serinephosphate and Zirconium L-(+)-Serinephosphate Phosphates

European Journal of Inorganic Chemistry, 1998
A layered derivative of α-zirconium phosphate containing L-(+)-serine covalently attached to the inorganic layer has been prepared by allowing Zr fluoro complexes to decompose in the presence of L-(+)-phosphoserine. On the basis of thermogravimetric weight loss and C,H,N elemental analyses, the layered compound obtained has been formulated as Zr[HOOCCH(

Preparation of luminescent layered zirconium phosphate nanocomposites by the layer-by-layer technique

Optical Materials, 2016
Abstract In the present work, photoactive cation N, N′-Dimenthyl-9, 9’-bisacridinium nitrate (BNMA) was assembled with exfoliated layered α-zirconium phosphate (α-ZrP) via an electrostatic layer-by-layer (LBL) assembly method. As a result, the luminescent films which were well-aligned and periodical had been successfully fabricated. Surprisingly, the

Oxide-phosphate layers with zirconium compounds on titanium

Protection of Metals, 2007
Layers of titanium and zirconium oxides and phosphates can be formed on the titanium surface in the aqueous baths containing polyphosphates and Zr(SO4)2 · 4H2O by the plasma-electrolytic method. The elemental and phase composition and the thickness of films, as well as the mechanism of their formation, depend on the molar ratio n = [polyphosphate]/[Zr4+

Intercalation of Glucosamine and Chitosan into Layered Zirconium Phosphates

Bulletin of the Chemical Society of Japan, 2006
Abstract Glucosamine was directly intercalated into γ-zirconium phosphate (γ-ZrP). The intercalation compound with a monolayer structure was obtained by the interaction between the 2-amino group of glucopyranose and the phosphate group in γ-ZrP.

Intercalation of insulating polymers into layered zirconium phosphates

Materials Chemistry and Physics, 1993
Abstract The ability of layered α- and γ-zirconium phosphates to intercalate directly some insulating oligomers (PEG 300 Da, PEG 600 Da) or polymers (PEO 2 × 10 5 Da, PEO 6 × 10 5 Da, PEI 2 × 10 5 Da) has been investigated. The intercalation was obtained by various synthetic strategies: the zirconium phosphates, pre-swelled with ethanol or butanol,

Preparation of some intercalation compounds of layered γ-zirconium phosphate and zirconium phosphate-phosphite

Solid State Ionics, 1991
Abstract Intercalation chemistry of layered zirconium phosphates is of interest for a better knowledge of their protonic conductivity. Intercalation compounds of γ-zirconium phosphate with some alkanols, n -alkylmonoamines and benzylamine have been prepared and characterized for their X-ray powder diffraction patterns, IR spectra and TG-DTA analyses.

Layered Zirconium Phosphate and Phosphonate as Heterogeneous Catalyst in the Preparation of Pyrroles.

ChemInform, 2003
Abstract Pyrroles may be prepared by condensation of alkyl and aryl amines and 1,4-diketones (Paal–Knorr reaction) under potassium exchanged layered Zirconium phosphate and zirconium sulfophenyl phosphonate catalyst in solvent free conditions.
