Abstract:
Ti02 is a versatile material that has found applications in a diverse range of devices
and applications such as solar cells, photocatalysts, gas sensors, photovoltaics,
hydrogen storage, Li-ion batteries etc. In recent years, highly-ordered onedimensional
Ti02 nanotubes have attracted much attention due to their distinctive
properties in these advanced functional devices. In this study, vertically aligned
Ti02 nanotubes were synthesized by anodizing a Ti foil in a non-aqueous electrolyte
containing ethylene glycol (97.5 wt.%), NH4F (2 wt.%) and deionized (DI) water (0.5
wt.%). Scanning electron microscopy (SEM) was used to characterize the morphology
of prepared nanotubes. Preliminary results showed the formation of tubular structures
with a diameter of 1.315 jim and the wall thickness of 209.1 nm. The results indicate
that the morphology of the nanotubes depends on the anodization voltage, anodization
time and electrolyte composition. In this study, it is expected to establish a relationship
between the nanotube morphology with anodization time, anodization voltage and
electrolyte composition. The outcome of this study will enable the synthesis of
Ti02 nanotube structures with tailored morphologies, for possible applications in a
wide range of advanced functional devices.
