微乳液静电纺丝法二氧化钛纳米纤维的制备及性能

文章导读

摘要以微乳液为前驱体，通过单轴静电纺丝法制备了具有多孔结构的二氧化钛纳米纤维。采用扫描电镜、X射线衍射、紫外可见漫反射光谱和氮气吸附解吸分析等对其进行了表征，并以亚甲基蓝和实际印染废水为目标物对其光催化性能进行了研究。结果表明纳米纤维的结构可以通过改变微乳液体系进行调控，当微乳液体系中加入混油相（石蜡和正己烷）时，制备得到的二氧化钛呈现出多孔和混晶结构，并具有优异的光催化性能。对亚甲基蓝溶液（MB）光催化降解率高达98%，对于实际印染废水光催化降解效果显著。该法制备过程简单，对特殊形貌光催化材料的制备提升性能具有重要的借鉴应用意义。

Abstract： Using microemulsion as the precursor, the porous structure of titanium dioxide nanofibers was prepared by uniaxial electrospinning. It was characterized by scanning electron microscopy, X-ray diffraction, ultraviolet visible diffuse reflectance spectroscopy and nitrogen adsorption and desorption analysis, and its photocatalytic performance was studied with methylene blue and actual printing and dyeing wastewater as targets. The results show that the structure of nanofibers can be adjusted by changing the microemulsion composition. When the mixed oil phase (paraffin and n-hexane) is added to the microemulsion system, the prepared titanium dioxide presents a porous and mixed crystal structure and has excellent photocatalysis performance. The photocatalytic degradation rate of methylene blue solution (MB) is as high as 98%, and the photocatalytic degradation effect of actual printing and dyeing wastewater is significant. The preparation process of this method is simple, and it has important reference and application significance for the preparation and performance improvement of photocatalytic materials with special morphology.
