| 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 c... |
