METHOD OF PREPARING PHOTOCATALYST BASED ON η-MODIFICATION OF VANADIUM-DOPED TITANIUM DIOXIDE, ACTIVE IN VISIBLE SPECTRUM REGION

摘要

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.;7 dwg, 3 ex
