Departmental Bulletin Paper
The visible light responsive TiO2 thin film photocatalysts were prepared by applying
a dip-coating process, for which the coating solution was prepared using titanium
tetraisopropoxide as a source material and different organic solvents. The nitrogen was
doped to the obtained TiO2 thin film during the calcination process as an agent for
visible light response. The surface morphology was analyzed by AFM and FE-SEM.
Nitrogen state in the lattice and crystalline stricture were measured by XPS and XRD,
respectively. Photocatalytic decomposition activity of methylene blue on the films was
also measured under visible light irradiation using the light emitting diodes.
