Abstract

Abstract: Mesoporous TiO₂ nanofibers have been synthesized by a new method that combines sol-gel chemistry and electrospinning technique. The obtained mesoporous TiO₂ nanofibers were characterized with scanning electron microscopy(SEM), X-ray diffraction(XRD), transmission electron microscopy(TEM) and nitrogen adsorption-desorption isotherms. The photocatalytic performance was evaluated by the photocatalytic degradation of Rhodamine B under UV light irradiation. The results show that mesoporous TiO₂ nanofibers exhibit higher photocatalytic activity compared with nonporous TiO₂ nanofibers.

Key words: Electrospinning, Mesoporous TiO₂, Photocatalyst
