TY - JOUR ID - TI - Effect of Anodization Duration in the TiO2 Nanotubes Formation on Ti Foil and Photoelectrochemical Properties of TiO2 Nanotubes AU - Asmaa Kadim Ayal PY - 2018 VL - 29 IS - 3 ICSSSA 2018 Conference Issue SP - 77 EP - 81 JO - Al-Mustansiriyah Journal of Science مجلة علوم المستنصرية SN - 1814635X 25213520 AB - In this work, the effect of anodizing duration on the morphology and photoelectrochemicalproperties of TiO2 nanotubes arrays (NTAs) has been investigated The samples were characterized by X-ray diffraction (XRD) and energy dispersive X-ray (EDX) to characterize their crystalline structure and compositional. Surface morphological and their dimensional variation was examined by field emission scanning electron microscopy (FESEM). The anodizing duration played a significant role in the formation of TiO2 nanotubes arrays. Moreover, the photoelectrochemical properties (PEC) were studied through photocurrent measurements. Optimum anodizing duration of 60 min at 40 V exhibited maximum photocurrent of 0.03 mA cm-2 under illumination of halogen light.
