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 ... Read more
