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.

formation TiO 2 nanorods. The structure of the sample was studied by X-ray diffraction and it revealed that the prepared TiO 2 exhibit a pure anatase phase. While the Fourier transform infrared spectroscopy (FTIR) was showing the vibration patterns in the spectrum of the sample. The morphology of sample was studied by scanning electron microscopy (SEM) and it showed that the synthesised TiO 2 made of nanorods with length about (698 nm) and a diameter (220 nm). IntroductionTitanium dioxide (TiO 2 ) is a semiconductor material that has a wide energy gap (3.2 eV) [1, 2]. Many studies have been focused in the present time on TiO 2 , due to its large surface area and characteristic electrical properties such as physical and chemical stability, high refractive index, low cost, non-toxicity and high photo-catalytic activities…etc. TiO 2 can be found in three crystalline phases: anatase, rutile both tetragonal structure and brookite with orthorhombic structure. Each of these phases have various chemical and physical properties depending on the composition of the atoms, thus leads to a varied performance in its application [3,4]. Anatase and brookite are metastable, while rutile phase is stable under certain conditions [5]. The anatase and brookite phases are easily turned to rutile phase during a high temperature [6,7]. Different morphologies of TiO 2 have been synthesized such as nanorods, nanowires, nanotubes, nanoparticles and nanobelts…etc. One dimension (1D) structures of TiO 2 especially nanorods, nanowires and nanotubes have been attracted a lot of attention due to the unique properties and great applications comparison nanoparticles. TiO 2 with (1D) structures have exhibited the faster process of generating electron-hole and a lower recombination rate comparison TiO 2 nanoparticle [8,9]
