Title: ZnO/SnO{sub 2} nanoflower based ZnO template synthesized by thermal chemical vapor deposition

Abstract

The ZnO/SnO{sub 2} nanoflower like structures was grown on a glass substrate deposited with seed layer using thermal chemical vapor deposition (CVD) with combining two source materials. The ZnO/SnO{sub 2} nanoflower like structures had diameter in the range 70 to 100 nm. The atomic percentage of ZnO nanoparticle , SnO{sub 2} nanorods and ZnO/SnO{sub 2} nanoflower was taken using EDS. Based on the FESEM observations, the growth mechanism is applied to describe the growth for the synthesized nanostructures.

  • The authors have been exploring a general route for preparing nanomaterials called template synthesis. The application of the template method to the preparation of microtubular battery electrodes is described here. The template method is used to prepare a current collector that consists of an ensemble of metal microtubules that protrude from a metal surface like the bristles of a brush. Chemical vapor deposition is then used to coat this high surface area microtubule-based current collector with a thin skin of the desired Li{sup +}-intercalation material, in this case TiS{sub 2}. In this way, a thin-walled tubule of TiS{sub 2} ismore » formed on the outer surface of each metal microtubule. The thin walls of these TiS{sub 2} tubes insure that the distance over which Li{sup +} must diffuse is small, and the high surface area insures that the current density is low. These microtubular TiS{sub 2} electrodes showed higher capacities, lower resistance, and lower susceptibility to slow electron transfer kinetics than thin film (control) TiS{sub 2} electrodes prepared form the same amount of TiS{sub 2}.« less
  • Titanium oxide (TiO{sub 2}) nanostructures such as nanorod arrays, nanotube arrays and nanoflower arrays have been extensively investigated by the researchers. Among them nanoflower arrays has shown superior performance than other nanostructures in Dye sensitized solar cell, photocatalysis and energy storage applications. Herein, a single step synthesis for rutile TiO{sub 2} nanoflower array films suitable for device applications has been reported. Rutile TiO{sub 2} nanoflower thin film was synthesized by chemical bath deposition method using NaCl as an additive. Bath temperature induced evolution of nanoflower thin film arrays was observed from the morphological study. X-ray diffraction study confirmed the presencemore » of rutile phase polycrystalline TiO{sub 2}. Micro-Raman study revealed the presence of surface phonon mode at 105 cm{sup −1} due to the phonon confinement effect (finite size effect), in addition with the rutile Raman active modes of B{sub 1}g (143 cm{sup −1}), Eg (442 cm{sup −1}) and A{sub 1}g (607 cm{sup −1}). Further, the FTIR spectrum confirmed the presence of Ti-O-Ti bonding vibration. The Tauc plot showed the direct energy band gap nature of the film with the value of 2.9 eV.« less
  • ZnO nanorods were synthesized by aerosol assisted chemical vapor deposition onto TiO{sub 2} covered borosilicate glass substrates. Deposition parameters were optimized and kept constant. Solely the effect of different nozzle velocities on the growth of ZnO nanorods was evaluated in order to develop a dense and uniform structure. The crystalline structure was characterized by conventional X-ray diffraction in grazing incidence and Bragg–Brentano configurations. In addition, two-dimensional grazing incidence synchrotron radiation diffraction was employed to determine the preferred growth direction of the nanorods. Morphology and growth characteristics analyzed by electron microscopy were correlated with diffraction outcomes. Chemical composition was established bymore » X-ray photoelectron spectroscopy. X-ray diffraction results and X-ray photoelectron spectroscopy showed the presence of wurtzite ZnO and anatase TiO{sub 2} phases. Morphological changes noticed when the deposition velocity was lowered to the minimum, indicated the formation of relatively vertically oriented nanorods evenly distributed onto the TiO{sub 2} buffer film. By coupling two-dimensional X-ray diffraction and computational modeling with ANAELU it was proved that a successful texture determination was achieved and confirmed by scanning electron microscopy analysis. Texture analysis led to the conclusion of a preferred growth direction in [001] having a distribution width Ω = 20° ± 2°. - Highlights: • Uniform and pure single-crystal ZnO nanorods were obtained by AACVD technique. • Longitudinal and transversal axis parallel to the [001] and [110] directions, respectively. • Texture was determined by 2D synchrotron diffraction and electron microscopy analysis. • Nanorods have its [001] direction distributed close to the normal of the substrate. • Angular spread about the preferred orientation is 20° ± 2°.« less

  • The renewed interest in the study of nanometer-scale materials has triggered intensive research on the synthesis of powders with improved properties. The characteristics of the starting powder are of paramount importance in the control of sintered microstructure and the resultant physical properties of the bulk body. Powders suitable for subsequent forming and consolidation should possess the following features: small size with a narrow size distribution, equiaxed morphology, highly pure chemical composition, single phase and nonagglomerated state. SiC ceramic is an important structural as well as functional material because of its strength, hardness, resistance to chemical corrosion, high thermal conductivity andmore » good electrical insulation. SiC powders with desired particle size and composition can be synthesized by a direct gas phase reaction process which offers many technological advantages over other formation methods in terms of small particle size, narrow size distribution, relatively pure chemical composition as well as good reproducibility. Though the roles of other parameters have been well documented and widely accepted by many investigators, the effect of gas flow rate still remains to be clarified. In his work, Yang concluded that the size of powders changes as a parabolic function of gas flow rate, while the morphology and composition of the powders are almost unaffected. However, present results indicate that both the size and morphology of the SiC powders obtained can be altered by modifying the gas flow rate, for which the underlying mechanisms have been explored.« less
