中文摘要：
以聚乙烯吡咯烷酮（PVP）为络合剂,与钛酸四正丁酯[Ti（C4H9O）4]和醋酸锰（Mn（CH3COO）2.4H2O）反应制得前驱体溶液,用静电纺丝法制备PVP/TiO2/Mn2O3纳米复合纤维,在马弗炉中经过煅烧处理过程,获得了TiO2/Mn2O3纳米纤维。采用扫描电镜（SEM）、热分析仪（TG-DTA）、X射线衍射仪（XRD）以及紫外-可见分光光度计对纤维的形貌、物相变化、组分和光吸收性能进行了表征。结果表明：TiO2/Mn2O3纳米纤维的直径较小,主要分布在100nm以下,经500℃高温煅烧即可得到TiO2/Mn2O3复合纳米纤维;并且Mn2O3的引入,有效地使TiO2的光响应范围由紫外光区拓展到了可见光区。
英文摘要：
Polyvinylpyrrolidone（PVP） used as a complexant was reacted with tetrabutyl titanate [Ti4（C4H9O）4] and manganese acetate（Mn（CH3COO）2·4H2O） to prepare precursor solution,and PVP/TiO2/Mn2O3 composite nanofibers were prepared by sol-gel processing and electrospinning methods.After calcining the above precursor fibers in muffle fumace,the TiO2/Mn2O3 nanofibers were abtained.The TiO2/Mn2O3 nanofibers were characterized by scanning electron microscopy（SEM）,thermogravimetry-differential thermal analysis（TG-DTA）,X-ray diffraction（XRD） and UV-Vis spectrophotometer.The results showed that it could be produced into TiO2/Mn2O3 nanofibers with a small diameter of 100 nm after calcination at 500 °C.The incorporation of Mn2O3 into titania dioxide could significantly extend the absorption by the photocatalysts into visible range.
