Analysis of Photocurrent Responses of Anodized TiO₂ Nanotubes Synthesized from Different Organic Electrolytes

Abstract:

Self-organized titanium dioxide (TiO₂) nanotubes (NTs) arrays were successfully fabricated via electrochemical anodization of titanium (Ti) foil in an organic electrolyte containing 5wt% of fluoride content. The present work compares two different organic electrolytes (glycerol and ethylene glycol) for the growth of self-organized TiO₂ nanotubes by using anodic oxidation strategy. The resultant TiO₂ NTs were then subjected to thermal annealing for manipulating the crystalline structure. The SEM images indicated changes in surface morphology of the TiO₂ NTs in different electrolytes. It was found that the NT’s dimensional was 56.00nm based on the SEM analyses. Both samples exhibited good photocurrent response; however, TiO₂ NTs synthesized in ethylene glycol electrolyte showed promising photocurrent response of 0.385 mA.
