Abstract:

A research-oriented comprehensive experiment, "fabrication, characterization and photocatalytic performance of N, F-codoped TiO2 nanotubes", was performed in Summer Research Training Program of Nankai University. Hydrogen titanate nanotubes prepared by hydrothermal method were impregnated by titanium sol containing NH4F to fabricate N, F-codoped TiO2 nanotubes (N, F/TiO2 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.

Key words: N, F-codoped, TiO2 nanotubes, Photocatalyst, Comprehensive experiment for the Summer Research Training Program
