混晶TiO2纳米纤维负载Ag 及其光催化性能OA北大核心CSCDCSTPCD
Preparation and Photocatalytic Properties of Ag-loaded Co-crystalline TiO2 Nanofibers
以聚乙烯吡咯烷酮和钛酸四正丁酯为前驱体,对静电纺丝法制备的TiO2纳米纤维进行不同温度的热处理,得到混晶TiO2纳米纤维,并进一步在不同浓度的AgNO3溶液中通过光还原法制备了Ag-TiO2复合纳米纤维.利用X射线衍射、扫描电镜、紫外可见漫反射光谱、荧光光谱等分析测试手段对产物进行表征,研究了热处理温度与不同 Ag 负载量的TiO2纳米纤维对罗丹明B降解性能的影响.实验结果表明,当热处理条件为600℃反应1 h时,TiO2纳米纤维具有最佳光催化活…查看全部>>
In this paper,co-crystalline TiO2 nanofibers were fabricated via electrospinning with post-calcination using polyvinylpyr-rolidone and tetra-n-butyl titanate as precursor,and Ag loaded TiO2 nanofibers were subsequently prepared with photo-reduction. The obtained samples were characterized by X-ray diffraction,scanning electron microscope,UV-vis absorption spectra and photolu-minescence spectra,and the photocatalytic activities of these samples were tested th…查看全部>>
