Abstract

Abstract:

An experiment "Doping and Photocatalytic Performance of TiO₂ Nanopowder" was performed in inorganic comprehensive laboratory for Boling Class of Nankai University. After the dopant precursors and corresponding contents were determined by the students, different elements doped TiO₂ powders were prepared by sol-gel method, and characterized by scanning electronic microscopy, transmittance electronic microscopy, powder X-ray diffraction and UV-Vis diffuse reflectance spectroscopy. The photocatalytic performances of the prepared catalysts were monitored by the degradation of methyl orange as the simulated wastewater to select the superior ones for photocatalytic water splitting test. Through this comprehensive experiment related to research frontier, the students in Boling Class can obtain basic research training and their scientific literacy can be improved.

Key words: TiO₂ nanopowder, Doping modification, Photocatalyst, Boling Class, Inorganic comprehensive laboratory
