摘要: The present invention relates to a titanium dioxide composition modified with urea in the stage of hydroxide precipitation from an aqueous solution. solution, contains mixture dissolved sulfate salts, including titanyl sulfate, following hydrothermal treatment precipitated its mother liquor. modification said is carried out basic silica sol formed or dried dioxide. characterized by enhanced thermal and stability pore structure, developped mesopore decreased sulfur content specific surface area pores diameter up 490 m2g-1 for calcined material at temperature 800 °C 3 hours.
