METHOD OF PREPARING PHOTOCATALYST BASED ON η-MODIFICATION OF VANADIUM-DOPED TITANIUM DIOXIDE, ACTIVE IN VISIBLE SPECTRUM REGION Russian patent published in 2015 - IPC B01J37/34 B01J37/08 B01J21/06 B01J37/00

Abstract RU 2540336 C1

FIELD: chemistry.

SUBSTANCE: method of preparing photocatalyst based on η-modification of titanium dioxide consists in the following: titanium dioxide doping is carried out by introduction of water solutions of vanadyl nitrates (VO(NO₃)₂) into reaction mixture in the course of titanium dioxide synthesis from solvated titanyl sulfate after formation of semiproduct of titanyl sulfate hydrolysis - stable titanium dioxide hydrosol.

EFFECT: increased sensitivity of η-modification of titanium dioxide to visible light with simultaneous increase of its photocatalytic activity and energy efficiency of technology of its obtaining.
