Article Preview

Nanometer titanium dioxide films supported on glass, quartz, molybdenum, and aluminum were prepared by sol-gel method. The loaded titanium dioxide films were characterized by atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and photocatalytic degradation of aqueous crystal violet. The titanium dioxide films supported on different substrates were all composed of polycrystalline nanoparticles, which belonged to single-phase anatase, and displayed different morphology after sintering at 773 K for 1 h. Some elements in the substrate made of noncrystal appeared on the surface of titanium dioxide films. The experiment about basic crystal violet degradation displayed the photocatalysis activity of titanium oxide films supported on the molybdenum was better.
