CATALYST BASED ON TITANIUM MICROPARTICLE POWDER Russian patent published in 2023 - IPC B01J21/06 B01J37/34 

FIELD: catalytic chemistry.

SUBSTANCE: catalyst for the catalytic photodestruction of organic and inorganic compounds in a solution based on a powder of titanium microparticles is proposed, characterized by the fact that it is an active layer on the surface of titanium metal particles - the catalyst carrier, with a thickness in the range of 15÷25 nm in the form of a phase mixture of TiN, TiON, TiO₂, with the content of components along the depth of the layer from the surface to the core of the carrier particle in the range of 0÷30 mol.%, 0÷23 mol.%, 100÷47 mol.%, respectively, and with distance from the surface of the catalyst layer, the concentration of TiN increases, and the concentration of TiO₂ decreases. A method for producing a catalyst based on powder from titanium microparticles is also proposed.

EFFECT: production of a photocatalyst with high efficiency in reactions of catalytic photodestruction of organic and inorganic compounds in solution.
