Porous materials

The text discusses zeolites as crystalline hydrated aluminosilicates with a precisely defined structure, containing well-ordered cavities and channels through which molecules of specific sizes can pass. This is why they are also referred to as molecular sieves. The porous nature of the structure contributes to their large specific surface area, with the total surface area of the pores being much greater compared to their external surface. The combination of crystal structure, specific sorption, and catalytic properties makes molecular sieves widely used in the petroleum refining and petrochemical industry, as well as in the production of detergents, desiccants, gas separation systems, ecology, and emerging high-tech fields such as electronics, optics, sensor technology, etc. The catalysis research group at the institute is involved in synthesizing various zeolite structures from both pure chemicals and coal ash. They also extensively study and characterize various natural representatives. Due to the crystal nature and large specific surface area of zeolite materials, their focus is on developing highly active catalytic systems for environmentally important processes. By modifying zeolite structures with different active phases, they achieve the formation of zeolite-supported catalysts with applications in heterogeneous catalysis for the oxidation of carbon monoxide and environmentally hazardous volatile organic compounds.
