Interaction of Titanium (IV) Chloride Vapor with Cotton Cellulose and Catalytic Properties of the Titanium Dioxide Obtained

Abstract

The slow (8-10 days) interaction of TiCl^sub 4^ vapors and dry cotton cellulose has been studied. The process is compared to the liquid phase one. In both cases titanium oxychlorides are mainely formed on the surface of the cellulose fibers at room temperature. Heating of such fibers in air at 500 °C produces long anatase titania deformed hollow fibers consisted of fine films of 100-200 nm thickness. The BET surface of the fibers is of 25.6 m^sup 2^/g including micropores surface of 5.3 m^sup 2^/g, and a pore volume of diameter less then 451 nm is of 0.078 cm^sup 3^/g. The efficient photocatalytic oxidation of methylene blue over synthesized titania fibers is demonstrated.
