METHOD OF PRODUCING PHOTOCATALYTIC COMPOSITES OF SPHERICAL LAYERED STRUCTURE FOR CLEANING WATER BODIES AND PHOTOCATALYTIC COMPOSITES TiO-Ag-SiO OBTAINED BY METHOD Russian patent published in 2024 - IPC B01J21/08 B01J21/06 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing spherical photocatalytic composites which can be used to clean water bodies. Disclosed is a method of producing photocatalytic composites of a spherical layered structure, comprising preparing a film-forming solution, it is deposited by immersion on a template with exposure of the template in solution for 6 hours at room temperature, followed by staged thermal treatment and exposure to ultraviolet radiation. Template used is a macroporous carboxyl ionite of the Tokem-200 brand with a divinylbenzene matrix, saturated with Ti⁴⁺ and Ag⁺. Obtained photocatalytic composites are also disclosed.

EFFECT: photocatalytic composites obtained using the disclosed method provide decomposition of molecules of organic dyes and pathogenic microflora of natural water.
