“…31 Activation of adsorbed species in the growing particles may also play a significant role, as interfacial reactions are particularly susceptible to microwave irradiation. 32 Interestingly, microwave-assisted synthesis can be carried out in domestic microwave ovens, [33][34][35] reproducible results being achieved as long as the amount of reagents, the irradiation time and the resting periods between irradiation intervals are adequately controlled. [36][37][38][39][40] The use of domestic apparatus has the advantage of lower cost whereas ovens specifically designed for laboratory operation allow temperature and pressure control.…”

Nanocrystalline anatase was synthesized, using both domestic and laboratory microwave ovens, from different precursors. Nanoparticulate anatase was obtained after microwave irradiation of tetra-butyl orthotitanate solution in benzyl alcohol. As-synthesized samples have orange color due to the presence of organics that were eliminated after annealing at 500°C, whereas the size of small anatase nanocrystals (around 8 nm) was preserved. Other nanocrystalline anatase samples were obtained from hexafluorotitanate-organic salt ionic liquid-like precursors. In this case, use of a domestic microwave oven and very short processing times (1-3 min irradiation time) were involved. Good specific capacity values and capacity retention at high C rates for insertion/deinsertion of Li 1 were recorded when testing such nanoparticles as electrode material in lithium cells. The electrochemical performances were found be strongly dependent on the phase composition, which in turn could be tuned through the synthetic procedure.

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]

Simple and low temperature hydrothermal process is employed to synthesize exotic nanostructures of TiO2. The nanostructures are obtained merely by changing the nature of the precursors and processing parameters. The chloride and isopropoxide salts of titanium are used to grow high quality thin films comprising anatase nanocorals, rutile nanorods and rutile nanoflowers respectively. A novel route of addition of room temperature ionic liquid (RTIL) is used to synthesize hitherto unexplored nano-morphologies. The Bronsted Acidic Ionic Liquid [BAIL] 0.01 M, 1: 3-ethoxycarbonylethyl-1-methyl-imidazolium chloride [CMIM][HSO4] RTIL directed growth of TiO2 flowers with bunch of aligned nanorods are obtained. The structural, optical and morphological properties of hydrothermally grown TiO2 samples are studied with the different characterization techniques. The influence of these exotic nano-morphologies on the performance of dye sensitized solar cells (DSSCs) is investigated in detail. It is found that [CMIM][HSO4] can facilitate the formation of novel nanoflower morphology with uniform, dense, and collectively aligned in regular petal like oriented TiO2 nanorods and hence improves the dye adsorption and the photovoltaic performance of DSSCs, typically in short-circuit photocurrent and power conversion efficiency. A best power conversion efficiency of 6.63% has been achieved on a DSSC based on nanoflowers (TNF) film obtained from a [CMIM][HSO4] solution.
