Synthesis of the nanocomposite SnO2-Au x0 -(H3PW12O40)y·nH2O layers on the silica surface by the layer-by-layer method

Conditions for the synthesis of the SnO₂-Au _x ⁰-(H₃PW₁₂O₄₀) _y ·nH₂O nanocomposite layers by the method of ionic epitaxy were determined for the first time. The layers we investigated by the method of scanning electron microscopy, energy dispersion microanalysis, UV and IR Fourier transmission spectroscopy. On the basis of the experimental data conclusions were drawn on the composition and structure of the synthesized layers. Original Russian Text ? L.B. Gulina, V.P. Tolstoi, K.B. Semishchenko, E.V.

Layers of nanocomposite FeOOH-xH3PW12O40 synthesized by ion-colloid layering

For the fi rst time the conditions of synthesis by ion-colloid layering of layers of nanocomposite FeOOH—xH₃PW₁₂O₄₀ on the surface of silica were defined using successively adagulation of FeOOH colloidal particles, and adsorption of H₃PW₁₂O₄₀. Investigation of the synthesized layers was carried out by scanning electron microscopy, X-ray microanalysis, UV and Fourier transmitting infrared spectroscopy.
