Abstract
In this project, anatase phase titanium dioxide (TiO2) nanofibers (NFs) are successfully fabricated using the homemade electrospinning (ES) method. This study
aims to fabricate uniform and high quality anatase TiO2/polyvinylpyrrolidone (PVP) NFs on the glass substrate. A number of parameters were studied for the development of best form of nanofibers; the most suitable/optimised parameters for
the fabrication of hydrogen gas sensor device were found at room temperature. Xray
diffraction (XRD) patterns show sharp and well-defined peaks identified as
anatase phase. Field emission scanning electron microscope (FESEM) images
revealing the formation of nanofibers are investigated. Surface topography
observations by atom force microscopy (AFM) indicate that the roughness is
improved by effect of the parameters selected and optical properties were measured
using ultraviolet-visible-near infrared (UV-Vis-NIR.) spectrometer.
