Fabrication of Platinum Nanowires via Electrodeposition of Platinum-Phenothiazine Complex in freshly prepared Anodic Aluminium Oxide Template

Porous anodic aluminum oxide film with self-ordered character, has been widely used as the template for fabricating nano-structural. materials. In this study highly ordered anodic aluminum oxide template was fabricated phosphoric acid by the two-step anodic-oxidation process. The anodizing voltage was maintained at 69 V. The results showed that 20 % phosphoric acid and 5 degrees C are suitable to prepare anodic aluminum oxide templates with a pore diameters of 130 nm. The fabricated anodic aluminum oxide films then subjected to post electrodepositing of Pt nanowires from freshly prepared Pt-phenothiazine complex; a forest of nanowires with a diameter nearly closed to the started anodic aluminum oxide pores sizes achieved. The morphology and surface of the anodic aluminum oxide films were examined before and after electrodepositing by scanning microscopy, atomic force microscope and X-ray diffraction spectroscopy.
