Undoped and Fe-doped TiO2 nanostructures have been successfully grown on Pt-coated quartz and Si (100) substrates using vapor-liquid-solid (VLS) growth method. The scanning electron microscopy (SEM) image showed that TiO2 grew in nanowires (NWs) with diameters of 200–400 nm and lengths greater than 12 μm. However, the morphology of Fe-doped TiO2 consists of chunk shaped nanoparticles (NPs). The X-ray diffraction analysis for undoped TiO2 NWs clearly showed the formation of tetragonal rutile TiO2, whereas for the Fe-doped TiO2 NPs it showed orthorhombic TiO2 phase and there are no crystalline peaks for iron or iron oxide. The refractive index and extinction coefficient values of undoped and Fe-doped TiO2 nanostructures were derived from the ellipsometric measurements. Enhanced photocatalytic activities were obtained for undoped and Fe-doped TiO2 nanostructures. The obtained results may find potential applications in optical devices and degradation of organic wastes.
