Directions of investigations

Investigation of chemical functionalization of silica surface, surface chemistry and physicochemical properties of synthesized silica materials. Directed design of active centers of sorption of ions and molecules in the surface layer of disperse silica to obtain specific and selective functional materials. Study of various sorption processes carried out with the participation of the surface of highly disperse oxides.


Main results for the recent years

Chemical approaches to the functionalization of highly disperse silicas for the synthesis of specific sorbents of toxic oxyanions, components of pesticides, aromatic organic compounds, for encapsulation of medicinal and biologically active substances, obtaining pH-sensitive silica materials are proposed.

Mesoporous silicas, the inner and outer surfaces of which are completely covered with grafted functional groups of β-cyclodextrin, were synthesized. They absorb nitrate-, orthophosphate- and orthoarsenate-anions, as well as aromatic organic compounds from aqueous solutions. Due to their mechanical strength, hydrolytic, chemical and thermal stability, kinetic parameters of sorption, these β-cyclodextrin-containing silicas can be used repeatedly for the absorption and concentration of toxic impurities, as well as their rapid analysis. The decisive role of complementarity of surface active centers and sorbed substances in improving kinetic and equilibrium sorption parameters has been proven.

The methods of chemical immobilization of indicator azo dyes (methyl red and alizarin yellow) on the surface of silica carriers have been proposed. It has been proven that indicator azo dyes grafted on silica surface retain the ability for color transition at changes of the medium pH. The obtained chemically stable pH-sensitive materials are perspective in the processes of control of medium acidity or selective recognition of organic molecules.

The formation of cetyltrimethylammonium bromide micelles has been studied in the presence of methyl red and alizarin yellow. It has been shown that micellar aggregates with solubilized azo dyes can be used as templates in sol-gel synthesis of MSM-41-type silica materials for regulation of theirs structural parameters. Templated sol gel synthesis of mesoporous silicas of MCM 41 type has been realized in the presence of methyl red and alizarin yellow as cotemplates and prepared on their basis silanes as structure forming components. It has been found that synthesized materials have improved structural characteristics and they are promising in sorption of acid dyes from aqueous solutions.

The acid-base properties of nanocrystalline titania and ceria have been studied. Equilibrium reaction constants of protonation, ionization and interaction of oxide functional groups with background electrolyte ions are determined. Quantitative characteristics of adsorption of amino acids, biogenic amines, deoxyribonucleic acid and its components (bases, nucleosides and nucleotides) from aqueous solutions on the surface of titanium and cerium dioxides are obtained. Quantitative parameters of adsorption are calculated in terms of surface complexation theory. This approach allows to characterize adsorption processes as the formation of complexes on the surface of oxide sorbents. It was found that the degree of interaction of nucleic bases and nucleosides is determined by the presence of functional groups: molecules that include amine and ketone groups are sorbed better than compounds with one type of substituents in the heterocyclic ring. They form outersphere complexes on the oxide surfaces, the components of which are connected by hydrogen bonds. Nucleotides and nucleic acid, which contain phosphate residues, are sorbed on the oxide surfaces with the formation of outer- and innersphere complexes due to electrostatic and covalent bindings. .
