The observed XRD pattern confirms the formation of pure SnO2 polycrystalline phase, corresponding to a tetragonal crystal system with P42/mnm space group, and is found to be ...

2012年7月27日 · X-ray diffraction (XRD), field emission scanning electron microscopy, and transmission electron microscopy (TEM) were employed to characterize the as-prepared product, and optical property was studied by UV-visible diffuse reflectance spectroscopy (DRS).

Photodegradation of gas phase benzene by SnO2 nanoparticles has been studied in humid air, dry air and N2 by using a tubular photoreactor. The SnO2 nanoparticles are synthesized by the...

2020年4月27日 · To identify the crystalline structure and crystallite size of the prepared NPs, XRD studies were carried out using X’Pert PRO Wide Angle X-Ray Diffraction (WAXD) using Cu-kα source with voltage 40 kV and current 30 mA in the 2θ range 20° to 90° at a scan speed of 2°/min. The obtained XRD pattern of Sn4, Sn5 and Sn6 is shown in Fig. 1.

2020年6月10日 · The structural characterization was performed with X-ray diffraction (XRD) measurements of the dried powder samples using a PANalytical Empyrean equipment, with a copper tube (λ = 1.5418 Å), Ni...

Structural characteristics were determined using X-ray diffraction (XRD) analysis. The XRD analysis confirmed the presence of various phases of $ { {\rm TiO}_2}$ T i O 2 (anatase and rutile)...

Abstract: SnO2 is n-type semiconductor and a transparent conducting oxide, and has apt properties in a gas sensing material, photovoltaic cells, fuel cells, batteries etc. In the present work SnO2 nanoparticles were synthesized by two different methods using different precursors.

The XRD results demonstrated the pure crystalline structure of the synthesized SnO2 nanoparticles, there are no other peaks detected in the experimental XRD pattern. After doping with MnO2, the XRD patterns indicated that the SnO2 crystal structure doesn’t affected at all MnO2 ratios (2, 4, 6 and 8 wt. %) as shown

2002年5月1日 · They found that a little deformation in the tin matrix of SnO 2 caused by the oxygen deficiency can induce the appearance of a layered structure, which is manifested by anisotropy in the XRD line widths, with the 101 line being the narrowest one. Also, the layered structure leads to the increase in crystallite sizes, and decrease in line ...

Abstract: Tin oxide (SnO2) undoped and Cu doped nanoparticles were synthesized by chemical process using low-cost tin chloride as the starting material. The crystal structure, particle size and optical properties of the nano particles were investigated by X-ray diffraction (XRD), and UV absorption spectroscopy.
