摘要
Abstract
In this paper,co-crystalline TiO2 nanofibers were fabricated via electrospinning with post-calcination using polyvinylpyr-rolidone and tetra-n-butyl titanate as precursor,and Ag loaded TiO2 nanofibers were subsequently prepared with photo-reduction. The obtained samples were characterized by X-ray diffraction,scanning electron microscope,UV-vis absorption spectra and photolu-minescence spectra,and the photocatalytic activities of these samples were tested through photocatalytic degradation of rhodamine B aqueous solution.The results show that the TiO2 nanofibers calcined at 600 ℃ exhibit superior photocatalytic activity,in which the mass ratio of anatase and rutile is about 93∶7.The photocatalytic activities of TiO2 nanofibers were obviously improved by appropriate amount of Ag loading and the apparent rate constant,k,of the Ag-TiO2 nanofibers for degradation of rhodamine B is about 3.81 times of that of commercial TiO2 P-25.关键词
