AB  - Our previous experiences with incorporation of polyoxometalates (POMs) ill different substrates have been very successful, because new nanocomposites with better conductive, catalytical and biochemical characteristics have been obtained. The results of intercalation of different mass% of ammonium decavanadate (ADV) in Al-pillared interlayered clays (Al-PILCs) are presented. The Al-PILCs were prepared using natural raw material, bentonite, containing a high percentage of montmorillonite (MM). Synthesis of ADV has been described in a previous paper. The structure of ADV hexahydrate was determined at low temperature, 100 K. A kappa refinement was performed to estimate the atomic charges. A sol-gel procedure was applied to obtain Al-PILCs composite intercalated with ADV hexahydrate (from 2 to 5 mass% of ADV). Structure and morphological properties of the new material, a nanocomposite of Al-PILCs-ADV, were investigated by X-ray powder diffraction (XRPD) and atomic force microscopy (AFM). To understand better how ADV is incorporated in the MM substrate, specific surface areas, pore structures and pore distributions were determined. Electrical and dielectric properties of the new materials were investigated by thermally stimulated depolarization currents (TSDCs) and broadband dielectric relaxation spectroscopy (DRS). The electrical conductivity of the nanocomposite was found to increase, in relation to MM, by intercalating with a small amount of ADV. (C) 2008 Published by Elsevier Ltd.

AB  - It is known that various polyoxovanadates interact specifically with enzymes, which is the main way of their biochemical activity. Therefore we have synthesized ammonium decavanadate, (NH4)(6)V(10)O(28)(.)6H(2)O. The novel compound was characterized by elemental and thermal analysis, X-ray powder and single crystal diffraction and IR and Raman spectroscopy. Its conductive properties have been studied, too. The spectroscopic analysis has shown the presence of hydrogen bonds of different strengths. In order to improve the biochemical activity of this compound and having in mind the presence of strong hydrogen bonds, we essayed the synthesis of complex of polyoxovanadate with alanine. The obtained product was characterized by the mentioned methods.
