FIELD: process engineering. n SUBSTANCE: invention relates to production of photocatalysts. Proposed method consists in preparing water solution of titanyl sulphate with concentration of 0.1-1.0 mol/l, adding acid thereto obtain concentration of 0.15-1 mol/l, hydrolysis of obtained solution in hydrothermal conditions at 100-250°C for 0.5-24 h, and drying of produced suspension of porous titanium dioxide. n EFFECT: production of porous photocatalyst with high specific surface and photocatalytic ctivity. n 6 cl, 4 tbl, 2 dwg, 4 ex |
