Synthesis and Characterization of Anatase TiO2 Nanofibers using Electrospinning Method

Abstract

TiO2 nanofibers with anatase structure were synthesized by an electrospinning method. Morphology and the nanostructure of the crystalline TiO2 nanofibers were characterized by means of x-ray diffraction (XRD), atomic force microscope (AFM), field emission scanning electron microscopy (FESEM). The energy gap was estimated and optical behavior was studied using UV-Vis spectroscopy, and Photoluminescence spectroscopy (PL). The effect of applied voltage parameter on TiO2 nanofibers was also studied.The results shows that the average diameter of the prepared nanofibersdecreases from (155- 48) nm with increasing the applied voltage from (15 - 21 kV) respectively.
