Composite nanostructured materials with regulated the physicochemical properties

Prototypes of new catalysts and photocatalysts based on newly synthesized nanoscale metal oxides obtained, kinetic regularities of redox processes in which they participate in waste water determined. The experimental dependence of the degree of photocatalytic purification in model wastewater and the nature of the pollutant concentration established. Substantiation of technological parameters of the liquid-phase oxidation-reduction processes wastewater from the pollutants of various origins determined.

The synthesis of high effective silicate materials for water basin protection from radioactive contamination

Application of surface and colloid chemistry modern approaches enable to purposefully increase sorptive capacity and selectivity of materials based on clay minerals by the porous structure features regulation and nature active sorptive sites changes. Large exchange capacity of the clay minerals is their important peculiarity, which is associated with well-developed heterovalent isomorphism and also by Si - OH and Al - OH functional groups on the side faces of alumosilicate structure packages.

Sol-gel synthesis of nanomaterials based on layered silicates for toxicants removal from waters

Highly effective sorbent materials were received with the help of modification of their surface by quaternary ammonium salts, inorganic polyhydroxocomplexes of metals and iron compounds for water purification contaminated with heavy metals and natural radionuclides. There were defined the basic principles of nanomaterials' synthesis on the base of dispersions of layered silicates with specified physical and chemical characteristics and structure.

The development of high selective sorptive ceramic materials for water basin protection from heavy metal natural radionuclide contamination

Actual high-selective porous ceramics and glass-crystalline materials with specified characteristics, structure and high operating abilities (advanced porous structure, high sorptive properties and selectivity, increased thermo- and acid- resistance, mechanical durability and others) for aquifer protection from heavy metals and natural radionuclides contamination were developed. Basic synthesis principles of these materials based on layered silicates dispersions, also regulation principles of their characteristics related to synthesis conditions and surface modification were specified.
