The production of nanomaterials with a developed porous surface reveals ample opportunities to create effectively modified ion exchange materials, catalysts, carriers and substrates. In this regard, of significant interest is the synthesis of nanomaterials based on vanadium compounds, which have an unique ability to complex formation, with the production of spatial partially ordered highly developed layered nanoscale structures. The article is devoted to the study of conditions for the modification of natural aluminosilicates by synthesized vanadium-containing xerogel to produce nanocomposite material having high catalytic properties. To substantiate the possibility of the synthesis of vanadium xerogel in the presence of ammonia, a theoretical and thermodynamic analysis of the equilibrium states of vanadium compounds was carried out using the HSC Chemistry 5.11 certified thermodynamic calculation program by Outokumpu Technology Engineering Research. It is shown that the physical and chemical properties of the obtained material are significantly influenced by the conditions of preliminary preparation of xerogel (temperature of heat treatment, “aging” of xerogel) and the mechanism of its introduction into the structure of zeolite.
