Main results for the recent years

The influence of complex oxides structure on their adsorption and catalytic properties was determined, as well as photodestruction and pyrolysis of organics at their surfaces. Ideas on structural hierarchy of nanooxides were developed. Changes in the oxide structure due to the synthesis effects or the influence of mechanical or thermal activation, media and adsorbates were elucidated. The influence of the morphology and chemical structure of complex nanooxides was analyzed with respect to the behavior of the colloidal systems. The mechanisms of reactions of organosilicon compounds (OSC) with a surface of silicas in gaseous and liquid media were analyzed with consideration of different solvent effects. The influence of the surface modification of silicas by OSC on the characteristics of the suspensions was studied depending on the modifier content and reaction conditions. The models of water adsorbed onto a surface of silica, mixed oxides, carbon-mineral adsorbents, polymers, etc. were developed using the experimental and theoretical methods. Cryoporometry methods based on the data of TSDC, DSC, NMR, as well as NMR-relaxometry and thermoporometry based on TG were used to study soft (biomaterials and bioobjects) and solid (oxides, carbons, composites) materials in weakly and strongly hydrated states. Comprehensive investigations of alumina, silica, titania, zirconia, germania, and complex oxides allowed to establish certain regularities of the “structure – property” types related to the pH dependence of the EDL structure, Debye screening length, particle size distributions, adsorption of small molecules and ions or polymers, catalytic destruction of adsorbed organics, dipolar and ionic relaxation of structured water and adsorbed polymers, etc. The methodology of calculations of the pore size distributions using complex pore models was developed for individual, complex and hybrid adsorbents. To solve coupled integral equations, the self-consistent regularization method with maximum entropy method was developed and implemented in investigations of texturally and chemically complex materials. The structure of adsorption complexes of biomolecules and adsorbed layer of biopolymers at a surface of different oxides, the mechanisms of adsorption and reactions were analyzed in detail using a set of experimental methods. Features of surface reactions with participation of vitamins, carbohydrates, glycosides, coumarins, flavonoids, chitosan, dextran, etc. were established for different oxides. A significant portion of the results was obtained in collaboration with colleagues from Universities from Lublin (Poland), Illinois, Cincinnati, New York (USA), Brighton (UK), Athens (Greece), Nancy (France), Queensland (Australia), Kyiv and several Institutions from NAS of Ukraine and RAS of Russia.
