The new technique for the TiO2 photocatalyst manufacturing with using titanium tetrachloride alcoholic solution was introduced. The ammonium titanate precursor was precipitated by double-jet method with using TiCl4 alcoholic and ammonium aquatic solutions. The TiO2 nanopowders were prepared by precursor calcinations at 400, 500, 600, 700 and 800o C. The photocatalytic activity was determined with dying photodegradation technique (methyl orange). The difference in adsorption ability of TiO2 dispersion reference to organic dyes was found. The conditions for the of TiO2 anatase effective photocatalyst synthesis were revealed.
