Abstract
The interaction of TiCl4 and cotton cellulose has been studied. Titanium oxichlorides grains are precipitated on the cellulose surface at room temperature, and solid film of titanium oxichlorides is formed on the cotton fiber surface at 100 oC. Heating of such fibers in air up to 600 oC produces titania hollow fibers. The acid pretreatment of cellulose before titanium oxichlorides precipitation allows the long solid hollow fibers of titania to be obtained. The obtained mesoporous material is characterized by surface area of 36 m2/g and average pore width of 12 nm.
