Obtaining of Hollow Fibers of Titanium Dioxide by Interaction of Titanium Tetrachloride with Cotton Cellulose
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 °С. Heating of such ﬁbers in air up to 600 °С 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 m <sup> 2 </sup> /g and average pore width of 12 nm.
