“…Three phases of titanium dioxide (TiO 2 ) are found in nature; anatase, rutile, and brookite [10][11]. Many researchers have proven that the titanium dioxide (TiO 2 ) in anatase phase exhibits higher performance for organic decomposition (reduce the electron--hole recombination) more than that of the other phases [12][13][14].…”

Titanium dioxide (TiO2) nanotubes with a highly ordered structure were grown by a self-organized anodization process. The photodeposition process was used to improve the visible light response of titanium dioxide (TiO2) nanotubes. The irradiation was carried out with 500 W halogen lamp for 1, 5, 15, 30 and 60 min in the mixed ethanol solution of antimony trisulfide (Sb2S3). The obtained samples were annealed at 250 °C for 30 min. The morphology of the fabricated sample was characterized by a field emission scanning electron microscope (FE-SEM). The phase of samples was determined by X- ray diffractometer (XRD). The weight percentages of a component in the sample were measured by X-ray fluorescence spectrometry (XRF). UV-Vis diffuse reflectance spectra (DRS) of the samples were recorded. All titanium dioxide (TiO2) nanotube samples prepared by anodization process were anatase phase. All composite titanium dioxide (TiO2) nanotube /Sb2S3samples were a crystalline phase. The percentage of Sb and S increase with increasing of photodeposition’s time. The increasing photodeposition of antimony trisulfide (Sb2S3) on titanium (TiO2) nanotubes from 1 to 60 min lead to increasing of photoabsorption property of the material in the visible region.

“…Three phases of titanium dioxide were found in natural; anatase, rutile, and brookite [10,11]. Anatase phase and rutile phase are more popular used as a catalyst for photocatalysis process than brookite phase because anatase and rutile phase have electron -hole recombination less than brookite phase [12]. Main factors affecting the photocatalytic efficiency included the absorption spectrum and specific surface area of the photocatalyst.…”

TiO2 nanotubes with a highly ordered structure were grown by a self-organized electrochemical anodization in the viscous organic electrolyte. The alteration pulse anodization waveforms were applied. The applied potentials were between positive of 20 V 10 min and a reverse voltage of 0 V or -5 V 20 sec. The morphologies of samples were examined using a field emission scanning electron microscope and focused ion beam field emission scanning electron microscopes (FIB-FESEM). The crystalline structures of the TiO2 nanotubes were confirmed by X-ray diffraction. The UV–Vis diffuse reflection absorption were recorded by a UV–vis spectrometer. All TiO2 nanotube samples prepared by pulse anodization technique were anatase phase and responded to UV region. The best-defined TiO2 nanotube morphology was obtained from the anodization condition: 20 V 10 min/-5 V 20 sec for 1 h. The thickness of the oxide layer increased with the increasing anodization time. All eight TiO2 nanotube samples responded to the light in the wavelength ranging from 190-360 nm which was UV region indicated the good photocatalytic property of these materials. Properties of anodized titanium dioxide nanotube from this work can be the useful indicators for the responsiveness of ultraviolet light which enhances the good property in photocatalytic process.
