Abstract RU 2748372 C1

FIELD: chemistry.

SUBSTANCE: composite material for a photocatalyst based on titanium dioxide doped with lead sulfide is proposed, characterized in that it contains components at the following ratio, wt%: titanium dioxide - 99.0 - 99.5, lead sulfide - 0.5 -1.0, with lead sulfide nanoparticles of size 8 -10 nm are evenly distributed on the surface and in the volume of the titanium dioxide matrix formed from nanoparticles with a size of 8-10 nm. Also proposed is a method for producing a composite material for a photocatalyst based on titanium dioxide doped with lead sulfide, which is described above.

EFFECT: development of a composite material for a photocatalyst that provides a high degree of degradation of stable chlorine-containing aromatic hydrocarbons, as well as a simple and technological method for its production.
