Erratum to: Nanoscale composite materials in the system SiO2– TiO2

Abstract

Nanoscale composite materials based on the SiO2–TiO2 system were prepared in the form of co-precipitated composites and core SiO2–shell TiO2 composites, with specific surface area 150–650 m2 /g and sorption volumes 0.1–1.0 cm3 /g. It is shown that variation of phase composition and morphology permits to change their structural-adsorption properties and nanocrystallites size after thermal treatment. It is discovered that co-precipitated composite materials differ from core SiO2–shell TiO2 composites by a component interaction degree. It determines the difference of the titan-containing component crystallization process and alteration of their structuralabsorption properties after thermal treatment. The results of the tests of composites as photocatalysts for Rhodamine B decomposition reaction, as catalysts of Hantzsch and Biginelli reaction, and as fillers in electrorheological fluids are shown.
