Electrochemical Fabrication and Characterization of Highly-Ordered Titania Nanotube Arrays

Article Preview

Abstract:

Highly-ordered titania nanotube arrays were fabricated in ethylene glycol polar organic electrolyte containing a certain amount of sodium fluoride. Series of patterned nanotube arrays with different outside diameter and aspect ratio were obtained via optimizing anodic voltage, the concentration of fluoride ion and reaction time. The as-prepared nanotube arrays were amorphous and transformed single anatase phase characterized by X-ray diffraction with annealing under the condition of 450oC for 3h. Cyclic voltammogram behaviors were discussed using electrochemical workstation. The pH value of electrolyte, the scanning rate, the crystal structure and morphology of the samples have a significant effect on the reductive/oxidative and H+ intercalation properties.
