Preparation,characterization and photocatalytic properties of Fe~(3+) doped TiO_2 nanofibers

The inorganic/organic composite nanofibers were prepared by electrospinning and sol-gel process,followed by high temperature calcining,and the resultant Fe3 + doped TiO2 nanofibers were characterized by various advanced apparatus in respect of the `morphology,crystal form,surface porosity structure and photocatalytic properties.The results showed that owing to the doping of Fe3 + the surface pore structures of TiO2 nanofibers were obviously improved,and the cell parameters and crystallinity were varied to certain extent.Doping proper amount of Fe3 + significantly enhanced the photocatalytic properties of TiO2 nanofibers.
