摘要
在南开大学化学学院本科生的暑期科研训练中,开展"氮氟双掺杂TiO_2纳米管的制备、表征和光催化性能研究"综合实验,以水热法制备的钛酸纳米管为前驱体,通过含氟化铵的钛溶胶对纳米管进行浸渍修饰,制备氮氟双掺杂的TiO_2纳米管,采用透射电镜、X射线衍射、TG-DTA、XPS、紫外漫反射等手段表征所得材料,以甲基橙溶液模拟有机废水,研究催化剂在紫外及模拟日光下的催化降解性能。通过贴近科研前沿的实验内容,对学生进行系统的初步科研培训,培养学生的综合科研能力。
A research-oriented comprehensive experiment,"fabrication,characterization and photocatalytic performance of N,F-codoped TiO_2 nanotubes",was performed in Summer Research Training Program of Nankai University.Hydrogen titanate nanotubes prepared by hydrothermal method were impregnated by titanium sol containing NH_4F to fabricate N,F-codoped TiO_2 nanotubes(N,F/TiO_2 NTs).The prepared catalysts were characterized by TEM,XRD,TG-DTA,XPS and UV-Vis DRS.By using methyl orange solution as simulated wastewater,the photocatalytic activities of the prepared materials under UV light and simulated sunlight were monitored.Through this comprehensive experiment related to research frontier,the students can obtain basic research training and their scientific literacy can be improved.
