Area(s) of expertise: 

The group focuses in the field of template synthesis of zeolites, zeolite-like silicates and phosphates of new generation, mesoporous molecular sieves etc. They could to develop approaches to creation of extra-large porous zeolites – microporous materials with pore diameter 8-12 Å, with the large elemental cell parameter – up to 2 nm, great adsorption capacity, availability of strong acidic sites. To propose and realize the approaches to structure formation and functionalization of moleular sieves connected with chemistry of templating action, with effect of solubilization, etc. They find the way and develop the method of the synthesis new generation of materials for application as catalysts and sorbents based on novel nanocomposites which combine adsorptive properties of the molecular sieves and magnetic characteristics of the iron oxide nanoparticles.
