METHOD FOR OBTAINING PHOTOCATALYSTS ACTIVE IN THE VISIBLE RANGE OF THE SPECTRUM WITH NANOSCALE TITANIUM OXIDES WITH THE STRUCTURE OF ANATASE AND A MIXTURE OF ANATASE AND RUTILE DOPED WITH TRANSITION METALS (Ni, V, Ag, Cu, Mn) Russian patent published in 2022 - IPC B01J37/04 B82B3/00 B01J21/06 B01J23/22 B01J23/50 B01J23/755 B01J23/72 B01J23/34 C01G23/08

Abstract RU 2776582 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for obtaining samples of nanoscale titanium dioxide with anatase structures or a mixture of anatase and rutile active in the visible range of the spectrum. The method consists in the fact that the reaction mixture is obtained by mixing and grinding powdered hydrated titanyl sulfate TiOSO₄×2H₂O, hydroperite (hydrogen peroxide clathrate with carbamide CO(NH₂)₂×H₂O₂) and salts of metal dopants V (VOSO₄×2H₂O), Ni (Ni(NO₃)₂×6H₂O, NiSO₄×7H₂O), Ag (AgNO₃), Cu (Cu(CH₃COO)₂), Mn (KMnO₄)), then the product is annealed at temperatures of 700-850°C for 1 h.

EFFECT: invention makes it possible to simplify the process of obtaining nanoscale titanium dioxide by reducing the number of stages and harmful reagents.
