Directions of investigations

Studies on regularities of chemisorption processes at surface layer of dispersed oxides, chemical and geometrical modification of solids, development of methods for immobilization of active compounds on inorganic matrices, investigation of equilibrium adsorption from solutions, forming of highly organized functional layers at the surface of inorganic supports, synthesis of metal nanoparticles in organic or inorganic porous nanoreactors. Practical orientation of works is associated with development of specific adsorbents based on modified oxides, immobilized catalysts, active fillers for polymeric systems, chemo- or biosensors, nanocomposites for various purposes.

 

Main results for the recent years

Novel methods for activation of the surface of functional organosilicas suitable for immobilization of wide variety of organic ligands and biologically active compounds have been developed. High-capacity and specific adsorbents for extraction and concentration of ions and molecules as well as efficient heterogeneous catalysts for oxidation processes have been synthesized on basis of chemically modified silicas.

Immobilization of ionene on the surface of the initial and modified silica particles directly at a moment when the polymer forms (in situ immobilization) has been carried out. The adsorbents containing quarternary nitrogen atoms and complexing groups at the surface layer have been synthesized via covalent binding of polyhexamethyleneguanidine and some of its organic amides with aminosilicas. The as-synthesized adsorbents demonstrate the pronounced anion-exchange properties, in particular, high adsorption capacity with respect to MoO42–, WO42–, Cr2O72–, VO3, AsO43–, PO43–, and AuCl4 ions. It has been elaborated the technique of sorptive X-ray fluorescence identification of trace amounts of molybdenum, tungsten, and vanadium applying silicas with chemically immobilized polyhexamethyleneguanidine derivatives for their pre-concentration.

The conditions of metal (Au, Ag, Pd, Pt) nanoparticles formation in the pores of chemically modified silicas with grafted silicon-hydride and aminogroups have been ascertained. The approaches of size regulation (3–20 nm) for surface-immobilized silver, gold, and palladium nanoparticles have been developed. In particular, it has been shown the promise for the use for these purposes the ordered silica matrices with various mesopore diameters and application of the methods of mosaic surface modification to form hydrophobic environment nearby the sites having the pronounced reducing properties. It has been found that silicas with deposited palladium nanoparticles already at metal concentration of 0.5 mass % enable both full conversion of CO to CO2 and full conversion of methane under the atmosphere of molecular oxygen and at relatively low temperature.

For modified silica fillers the ratio of surface organophilic and chemically active groups contents was found to effect essentially on structuring and properties of filled composites formed during copolymerization of acrylate and vinyl monomers. The role of aminogroups grafted to silica surface in formation of filled epoxypolymers has been studied. The nanocomposites based on 2-hydroxyethylmethacrylate and highly dispersed silica with various degrees of modification with methyl, vinyl, and silicon-hydride groups have been synthesized. The activation methods for carbon nanotube interface have been developed and the properties of filled with carbon nanotubes polystyrene and polyhydroxyethylmethacrylate have been studied.

It has been suggested and defended with Ukrainian patents the methods for synthesis of composite granules with wide-range variation of time for diclofenac and sodium diclofenac release due to application of modified silica with predetermined surface nature, matrices with various porous structure, and via preparation of biocompatible nanocomposites with chitosan. Amorphous state of diclofenac sodium adsorbed on hydrated silica surface was found to promote an increase in the rate of its dissolution.
