Effect of Electrolyte Composition in Electrochemical Synthesis of Self-Organized Tio₂ Nanotubes

Abstract:

In this paper, self-organized TiO₂nanotubes (TNT) were synthesized by electrochemical anodization in different electrolytes comprising acidic fluorinated aqueous electrolyte and organic neutral electrolyte. The structural, morphological and composition of TNT were characterized with XRD, FESEM and EDX. Compared with aqueous electrolyte, much smoother tubes with an increase of over 30 times in nanotube length can be obtained by anodization in organic electrolyte. Besides the high aspect ratio, variation of nanotube length within the array could be observed. Interestingly, under the same heat treatment condition, choice of electrolyte has an influence on the crystalline structure of TNT.
