Abstract

Abstract:

We utilized sol\|gel method to synthesize rutile TiO₂ directly from NH₃·H₂O and Ti(SO₄)2 at 70 ℃ temperature. According to the XRD, TEM, Raman results of the sample contains single rutile TiO₂ structure. The size of the nanoparticals is approximately 20 nm. Rutile TiO₂ particles have far better photodegradation efficiency on rhodamine B dyes than rutile TiO₂ particles obtained by thermal treatment, but a little lower photodegradation efficiency than P25 TiO₂ particles do.

Key words: titanium dioxide, sol-gel method, photocatalylic, rhodamine B
