Nanofibers are defined as fibres with sub-micron diameter. Due to their thickness they offer extremely large specific surface area. The most frequently mentioned ceramic material with nanofiber morphology is a titanium dioxide. The possibility of industrial use of TiO2 nanofibers is conditioned by a highly efficient continuous production technology. This is allowed by a modified NanospiderTM device. Titanium tetrabutoxide is used as the spinning solution. After spinning process, the nanofibrous layer consists from a mixture of organic and inorganic material, that’s why a subsequent calcination is necessary. During the calcination any organic components will be incinerated and pure titanium dioxide fibres with a crystalline structure are obtained. In the present work a high resolution scanning electron microscope and X-Ray diffraction were used for the assessment of the structure and phase composition of resulting TiO2 nanofibers.Keywords: calcination, nanofibers, photocatalysis, structure, titanium dioxide
