    Fabrication and characterization of TiO2 nano rods made by electrochemical deposition into anodic alumina template
    (UMT, Lhr, 2015) MUHAMMAD IKRAAM
    Highly ordered nonporous anodic aluminum oxide (AAO) nanorods were fabricated in oxalic acid using a steady voltage by the use of a two-step anodization procedure. To develop a high-aspect-ratio template filling process was adopted to form TiO2 nanorods. Scanning Electron Microscopy (SEM) images indicated that rods like TiO2 structures were sputtered onto the AAO template surface and TiO2 show evidence of fine filling results and clear crystal grain boundaries.Major and self-supporting TiO2 nanorods arrays were liberated through selectively get rid of the aluminum substrate and AAO template using a wet etching procedure with no breaking up or agglomeration after the drying practice. Template-deposited TiO2 nanorods indicate the appropriateness of the Direct Current (DC) electrophoresis as a successful method to fill the aluminum oxide templates.This process facilitated the speedy, straightforward synthesis of highly ordered TiO2 nanorods arrays through desired parameters such as diameter, density, and thickness determined using diverse AAO templates.The bold effect of acids used in changeable combinations based upon the researcher‘s skill, voltage settings and times of the three major electrolytes applied are also noted down and tabulated irrespective of the fact that the bulk of researchers have a tendency to use oxalic, phosphoric and sulfuric acid to produce nano-pores ranging in size from around 10 to 240 nm size structures.
