Preparation and characterisation of ultrafine and uniform TiO2 nanofibres

Ultrafine and uniform TiO2 nanofibres were prepared by electrospinning. The morphology of the nanofibres was characterised by field emission scanning electron microscopy, which showed that the nanofibres were composed of ultrasmall nanoparticles. The structure was characterised by X-ray diffraction and resonant Raman spectrum. The optical properties of the nanofibres were characterised by photoluminescence spectrum and ultraviolet visible spectrum. The results showed that anatase phase of TiO2 formed with the nanofibres annealed at 450 degrees C for 3 h and showed good optical characteristics.
