Abstract
In this study, titanium dioxide (TiO2) was synthesized using microwave method as rapid, uncostly and effective method. In order to study the effect of the solvent on the morphology of the prepared samples, two different solvents were used. The first solvent was ethylene glycol (EG, 99.8%) and the other was deionized water (DIW), while titanium isopropoxideTi[OCH(CH3)2]4 was used as TiO2 precursor. A commercial microwave oven was used with a power of 750 W and 5 minutes was selected as a duration of time preparation. The prepared specimens were annealed at 400 °C for 1 h. Diverse techniques were used in this study, such as X-Ray diffraction (XRD), field emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (FESEM-EDX) and Fourier transforms infrared spectroscopy (FTIR) to study the structures and morphology of the prepared TiO2. Surface area was measured using Brunaner EmmettTeller (BET) technique. The XRD results revealed that the prepared samples were a pure TiO2 in anataseface.
Noticeably, FESEM results show that the prepared TiO2 samples were nanorods-like shape with a length varied from 2 μm to 30 μm and a diameter varied from 500 nm to 6 μm when EG was used as a solvent. In contrast, spherical agglomerated nanoparticles with average diameters 20 nm were obtained when DIW was used as a solvent. The BET analysis revealed that the surface area of TiO2 nanorods was 151.413 m2/g, while it was 103.365 m2/gfor TiO2 nanoparticles.
