Titanium dioxide fibers (TFs) and gold/titanium dioxide nanocomposite fibers (Au/TFs) were fabricated through electrospinning. As observed from SEM, the TFs and Au/TFs appeared as continuous non-woven fibers with fiber diameters in the range of 80 to 130 nm. TEM images of Au/TFs revealed existence of gold particles, 14 to 18 nm in size. EDX result confirmed the existence of Au in Au/TFs samples. From XRD analysis, as-spun TFs were amorphous. After heat treatment, the prepared fibers transformed to anatase phase and the gold diffraction pattern became apparent. Applying the method of Kubelka-Monk on the UV-Vis reflection data, the energy gap of Au/TFs decreased from 3.20 to 3.08 eV, respectively.



Key words: Electrospinning, titanium dioxide fibers, gold/titanium dioxide nanocomposite fibers, energy gap.
