“…Later, the α-and γ-zirconium and titanium phosphates were extensively studied, and have been reviewed by Clearfield [11] and other authors [12][13][14], respectively. Later, an interest arose in nanoparticles (γ-ZrP/Si) and transition metal salts (i.e.…”

Abstract:The transition metal forms of α-zirconium-. titanium-, and hafnium phosphates were prepared by ion exchange method. Their structure was investigated by X-ray powder diffraction (XRPD) method. It was found that the transition metal containing phosphates have the same layered structure as the pristine tetravalent metal phosphates, except for the increase of interlayer distance from 7.6Å to ∼9.5Å. As a result of the incorporation of transition metals in the layers, the c-axis is increased from ∼15Å to ∼20Å (in the case of titanium phosphate to ∼25Å). All other parameters (a, b and β • ) are practically unchanged.

The crystalline structure of γ‐Zr(AsO4)(H2AsO4) × 2 H2O (γ‐ZrAs) has been refined by the Rietveld method. It has a monoclinic P21 layered structure built up from AsO4 tetrahedra and ZrO6 octahedra stacked along the 001 direction. The cell parameters are: a = 5.5752(6) Å, b = 6.8290(7) Å, c = 12.110(1) Å, and β = 103.03(1)°. The layered nature of γ‐ZrAs is confirmed by the intercalation of n‐alkylamines (CH3[CH2]nNH2; n = 0–5) as well as of cyclic amines (benzylamine, cyclohexylamine, piperidine, and pyridine). Among the linear amines, only with methyl‐, ethyl‐, and hexylamine is the maximum incorporation attained. With the cyclic amines, except in the case of pyridine, pure new phases are obtained, with the highest degree of intercalation being one mol of amine per mol of γ‐ZrAs.

Intercalates of VOPO 4 with several branched alcohols (2-propanol, 2-methyl-1-propanol, 3-methyl-1-butanol, 4-methyl-1-pentanol, 2-methyl-2-propanol, 2,2-dimethyl-1-propanol, 3,3-dimethylbutanol, 3-methyl-1-pentanol, 2-methyl-1-pentanol, 2-hexanol, 2-ethyl-1-butanol, 2-propyl-1-pentanol) were prepared and characterized by powder X-ray diffractometry and thermogravimetry. Only 2-propanol, 2-methyl-1-propanol and 3-methyl-1-butanol were directly intercalated into vanadyl phosphate dihydrate. The other inter-
