摘要：

使用溶胶-凝胶法和静电纺丝技术制备了有机无机复合纳米纤维，经高温煅烧后得到Fe3+掺杂TiO2纳米纤维。采用各种先进仪器针对纳米纤维的表面形貌、多孔结构、结晶性能以及光降解性能进行了表征和测试。研究发现：由于Fe3+的掺杂TiO2纳米纤维的表面多孔结构有了明显的改善；Fe3+掺杂还对纳米纤维的晶胞结构以及结晶度都产生了不同程度的影响；适量的 Fe3+掺杂可显著改善TiO2纳米纤维的光催化性能。

Abstract:

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.
