Abstract

The core-shell nanofibers consist of titanium dioxide and tin dioxide were fabricated by electrospinning method in order to enhance photocatalytic activity under ultraviolet (UV) irradiation. The morphology and microstructure of the produced nanofibers were investigated using scanning electron microscopy (SEM), transition electron microscopy (TEM) and X-ray diffraction (XRD). According to SEM images, the fabricated samples have core-shell TiO2-SnO2 structures with diameters ranging from 120 to 70 nm. The XRD analyzes show that synthesized nanostructures have a crystalline dominant phase after thermal treatment. Furthermore, the results of ultraviolet-visible (UV-Vis) spectroscopy show that the changes in absorption peaks of Rhodamine b, Methylene blue and Methyl orange have been considerably reduced in presence of core-shell nanofibers TiO2-SnO2. These results confirm that the photocatalytic properties of nanofibers eventually led to a reduction in concentration of the model dye.
