Original Abstract

Low temperature phase of titanium oxide (anatase) is known for its photocatalytic characteristics. It is obvious that this attribute is strongly connected with the surface area of the material. Therefore, the nanofibers are very promising type of structure in this case - despite their low volume they have very high specific surface. Electrospinning is quite fast and simple method for the preparation of the nanofibers. The technique is based on effect of the electrostatic field on a conductive liquid (usually organic) precursor. The precursor for preparation of the TiO2 nanofibers was composed of tetraisopropyl orthotitanate, stabilized by acetyl acetone, dissolved in ethanol. The influence of various parameters (chemical composition and viscosity of the precursor, spinning voltage, size of the emitor needle) on the fibers’ morphology were investigated. Data was analyzed by non-parametrical statistical test for discovering the most important parameters which influence the diameter of the TiO2 nanofibers. The influence of the calcination temperatures on the phase composition of the fibers was investigated, too.
