Abstract: |
TiO2 nanorods can be used as dye-sensitized solar cells, various sensor and photocatalysts. TiO2 nanorods are synthesized by a hydrothermal corrosion process in NaOH solution at 200 oC using TiO2 powder as a source material. We report on the synthesis of TiO2 nanorods in anatase, rutile and Ti8O15 phases and synthesis of TiO2 nanorods by incorporating with silver oxide and iron oxide dopant. We use Tetra Isopropy Ortho Titanate (TIOT), silver and iron Nitrate as amorphous precursors. The nanorods have been obtained using the sol-gel method and bases corrosion, by the simultaneous gelation of all cations. The morphologies and crystal structures of the TiO2 nanorods were characterised using field emission scanning electron microscopy (FE-SEM, HITACHI S-4160), atomic force microscopy (AFM, Easy Scan 2 Flex (Switzerland) and X-ray diffractometer (GBC-MMA 007 (2000) with Cu Kα1 radiation λ = 1.54056 Å). X-ray diffraction showed the formation of nano crystalline phases. Filled emission scanning electron microscopy (FE-SEM) revealed grains trend to make a rod shape from spherical particles. FTIR spectra show that Ti-O-Ti, Ti-O and Fe-O bonds are formed and indicate that titanium is in four-fold coordination with oxygen. The effects of chemical compositions and calcinations temperature on the surface topography and the crystallization of phases were studied. |
