We have studied chemical and phase compositions of the derivedproducts and their textured characteristics. We compared synthesized samples with theirmarket analogues and studied potential application for the production of heterogeneouscatalysts.Using of alcoholates of some metals as precursors of carriers for heterogeneous catalystsis rated today as the promising trend in the catalyst production.The present work is providing the physicochemical properties of individual andcompound oxides of Ce, La, Al, Zr, Mg, Cu, Co, Ni, Ba, Cr, Y. As initial re-agents forreceiving of alcoholates of metals served carbonates, acetates and nitrates, which wereexposed to interaction with separate alcohols and with their mixtures: isopropyl, n-butyl,octyl, isoamyl, etc. With the hydrolysis of individual or compound alcoholate of alcoholicsolutions, were accordingly derived individual or compound oxidation systems, which weredried and calcinated according to the given mode.We studied chemical and phase compositions, specific surface with the low-temperatureadsorption method (BET), porosity of synthesized samples, dimensional particle spectrum.For the study of thermo stability, the oxidation systems were subjected to thermal shock(at 1100 o С/4 hours) and the subsequent research of the specific surface and porosity.We carried out the comparative analysis of features of synthesized material with theirmarket analogue. The results indicate the future promising potential application of sol-gelmethod for deriving of oxidation systems as carriers of heterogeneous catalyst.318
