One-dimensional titanium oxides (TiO 2 ) nanorods have substantial applications in photocatalytic, nanoelectronic, and photoelectrochemical solar cells. These applications require large quantities of materials and a production technique suitable for future industry fabrication. We demonstrate here a new method of TiO 2 nanorods production from ilmenite sands (FeTiO3).
