Responding Depth of Photocatalytic Activity of TiO2 Self-assembled Films

Keywords： Responding depth

The electrostatically self-assembly method is getting strategically important to prepare multilayer thin films. With careful choice of component materials, this method should allow for the preparation of multilayer thin films with a variety of excellent technological properties. TiO2/PSS multilayer thin films with ordered structure were prepared by electrostatic self-assembly method. UV-Vis-NIR spectrophotometer, X-ray photoelectron spectroscopy (XPS),and atom force microscopy (AFM) were used to characterize the structure and performance of the multilayer films.Because electrostatically self-assembly method allows molecular-level control over the film composition and thickness,this paper studied the responding depth of photocatalytic activity of TiO2 self-assembled films in detail.
