Directions of investigations

Study of the regularities of the processes of chemisorption in the surface layer of disperse oxides, chemical and geometric modification of solids, including the use of template and sol-gel methods, development of methods of immobilization of active compounds on inorganic matrices, investigation of adsorption equilibria from solutions. Practical direction of work is related to the development of specific adsorbents based on modified oxides, heterogeneous catalysts, active fillers of polymeric systems, chemo- and biosensors, nanocomposites.

 

Main results for the recent years

TThe syntheses of nanoparticles of noble metals (Pd, Ag, Pt, Au) immobilized on chemically modified silica matrices with defined structural characteristics and surface nature were carried out. The approaches to regulate the sizes of immobilized nanoparticles have been developed due to the use of silica with different content of grafted silicon hydride groups, the variation of the concentration of ions of the corresponding metal in the solution, and application of matrices with different parameters of the porous structure. Modification in a fluidized bed reactor was found to provide preparation nanomaterials with a high content of hydridesilyl groups in the absence of catalysts and with minimal impact on the morphology of pyrogenic silica aggregates.

The adsorption characteristics and kinetic properties of complexing and ion-exchanging chemically modified silicas have been studied. Such adsorbents were obtained with the use of a one-stage Mannich reaction for the immobilization of organic phenol-type ligands, by anchorage of guanidine-containing polymers, by the implementation of oxidative polymerization of aniline and the formation of a layer of ionens on the surface of silica particles directly at the time of polymer formation (in situ immobilization). A significant decrease in the rate of desorption of sodium diclofenac was found when using highly dispersed chemically modified silicas as a carrier. It has been established that it is possible to control the degree of release of the drug over a wide time range by varying the porous structure and nature of the surface of the silica carrier and using a chitosan-based matrix, whose properties can be altered by introducing a crosslinking reagent, protonation or deprotonation of amino groups of a polymer. Dispersed composites based on ornidazole and the pristine and modified forms of pyrogenic silica, characterized by different degrees of release of the active substance, were obtained.

Composites of the mineral carrier-chitosan have been synthesized by crosslinking the adsorbed biopolymer and using covalent immobilization and sol-gel transformations. It was shown that organomineral compositions based on silica gel, clinoptilolite, saponite and chitosan exhibit the best adsorption properties for metal-containing oxoanions in comparison with adsorption of cations from aqueous solutions. By implantation of phosphinic acid on amino groups of chemically modified silica with the help of carbonyldiimidazole, a new phosphorus-containing adsorbent has been obtained that effectively absorbs uranium ions from the acidic medium, the sorption equilibrium is established within 1 h, and the sorption kinetics corresponds to the pseudo-second order model.

It was shown that silica composites with chitosan and carrageenan exhibit relatively high sorption capacities relative to dyes of anionic and cationic types, respectively, possessing satisfactory kinetic characteristics, which confirms the possibility of their effective application in the process of purification of technological solutions.

The luminescent properties of pyrolysis products of silica-based sol-gel composites with some organic precursors have been studied.

Use for chemical modification of the surface of pyrogenic silica the mixtures of polyorganosiloxane with alkyl carbonates was found to allow one to carry out chemisorption processes at the relatively moderate temperatures and to obtain modified silica with high content of grafted organic groups. The possibility of splitting the siloxane bond Si-O under the action of dimethyl carbonate in both organosiloxane and on the surface of silica has been proved.

The synthesis of composite materials based on silica and polylactic acid was carried out by graft polymerization with the opening of the L-lactide cycle. It was shown that on the basis of such biocompatible materials it is possible to create effective enterosorbents for the adsorption of toxic metal ions. Biocompatible composite materials suitable for the regulated delivery of anti-inflammatory drugs (diclofenac sodium, ibuprofen) have been developed on the basis of nanosilica and polylactic acid. Methods for the synthesis of composites of bactericidal action on the basis of dispersed modified silica and polylactide, which contain nanoparticles of copper oxide, silver or cerium dioxide were elaborated.

Methods of one-stage synthesis of mesoporous silicas with complexing and ion exchanging (amine, ammonium, thiol, thiourea and phosphonic) groups have been elaborated using sol-gel and template methods. Morphology of the obtained materials was studied using the electronic and atomic force microscopies, the composition and structure of their surface were determined by methods of vibrational and solid-state NMR spectroscopies. The sorption properties of synthesized materials with respect to the ions of some heavy, precious metals and actinides have been studied.

The spherical particles of organosilicas (average diameter 150-300 nm) with various functional (fluorine, nitrogen and sulfur-containing) groups in the surface layer were obtained by reaction of hydrolytic condensation of Si(OC2H5)4 with the corresponding functional alkoxysilanes in the ammonia medium. Using this approach, bifunctional modifying layers containing the groups ≡Si(CH2)3NH2/≡SiCH3 and ≡Si(CH2)3NH2/≡SiC3H7-n were deposited on the surface of the magnetic Fe3O4 particles. Nanocomposites with a magnetic core and a shell made of mesoporous silica obtained by the template method with amino and mercaptopropyl groups were created. The synthesized composites have a high sorption capacity for silver, lead and copper ions. It was found that the inclusion of cerium in the structure of ordered mesoporous silicas with acid functional groups increases the efficiency of such materials in the ethanol dehydration process.

The main factors influencing the value of the linkage of urease and cholinesterase and saving of their activities in the polysiloxane matrices, on the surface of the mesoporous silica and functionalized magnetite were established. Preparations with a high (50–90%) level linkage of the enzyme and the preservation of its activity (50–70%) have been obtained. The reactions of polycondensation of three and tetraalkoxysilanes were applied for the formation of sorption-active organosiloxane layers on the surface of a flat ceramic membrane on the basis of Al2O3. Using micellar templates and the Stober method, mono- and bifunctional polysiloxane materials with complexing groups were obtained and the factors influencing their structural-adsorption characteristics were studied. The obtained hybrid organic-inorganic materials are promising as high-capacity sorbents in the surface layer of ceramic membranes. .
