A novel method for synthesizing titanium oxide nanotubes and nanowires from liquid phase deposition in an aqueous solution at near-ambient conditions has been developed. The as-synthesized nanotubes and nanowires have been analyzed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). This synthesis method has also been expanded to include other metal oxides: tin oxide, zirconium oxide, and iron oxyhydroxide. This approach offers simplified nanocapabilities which could open a wider field of applications for low cost ceramic nanotubes and nanowires. Titanium dioxide nanotubes and nanowires composed of densely packed nanometer sized grains have been successfully deposited inside an anodic aluminum oxide template at near-room temperature (45 °C) from an aqueous solution using a simple, inexpensive, reproducible, and an environmentally friendly method. The aqueous solution was obtained by dissolving ammonium hexafluorotitante in a boric acid solution. The average length of the TiO2 nanotubes and nanowires is 2 µm with diameters from 60 - 250 nm depending on the template pore size. The nanotubes and nanowires were uniform, homogeneous, and without visible defects. Ions were hydrolyzed in an aqueous solution to produce metal oxides which adhered to the inner pores of the substrate. The growth rate and crystallinity can be controlled by careful manipulation of solution parameters and the surface functionality of the substrate.
