This document summarizes a study on the synthesis and characterization of titanium dioxide (TiO2) hollow nanostructures using a low-temperature hydrothermal route. Three hydrothermal methods were used to develop TiO2 nanotubular structures using rutile mineral powder as a starting material. Characterization with XRD, SEM and EDS showed that the fabricated TiO2 nanotubes had diameters ranging from 65-400 nm and lengths up to microns. The hydrothermal synthesis method allows control over the nanostructure morphology and is suitable for scaling up production of TiO2 nanotubes for applications in photoactive devices, sensors, and energy storage.
