    ZnTiO3 nanoparticles were prepared by a modified sol-gel method at the low sintering temperature of 550 Β°C. Titanium tetra isopropoxide and Zinc acetate dihydrate (C4H10O6Zn(H2O)2) materials were used as a source of titanium and zinc, respectively. The prepared nanopowders were characterized by means of X-ray diffraction (XRD), thermal gravimetric analysis (TGA), field emission Scanning electron microscope (FE-SEM) and Raman spectroscopy. The XRD patterns and Raman spectra revealed that in the temperature range of 550 to 800 Β°C, ZnTiO3 is the only zinc titanate compound exists in the samples.

    SnO2/TiO2 nano particles are novel wide band gap semiconductors with modified applications of SnO2 and TiO2 in some fields including gas sensing, photo catalytic, solar cells and so on. The Co-doped SnO2/TiO2 nano particles were obtained via sol-gel method with different amounts of doping material as 2.5 %, 6 % and 10 mol %. The crystallite sizes of resulting material were from 3.8 nm for 0.1 wt % Co-doped SnO2/TiO2 to 19.1 nm for un-doped. Morphology and nanostructure of the crystalline SnO2/TiO2 nano particles were characterized by means of X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), Thermal gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDX). It has been shown that fine semiconductor nano structures were formed. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/933

    A Simple Sol Gel Protocol Towards Synthesis Of Semiconducting Oxide Nanomaterial

    Nanostructured Tin oxide (SnO2), powders was synthesized by employing a novel Sol-gel protocol at RT. A wide variety of techniques such as energy – dispersive spectroscopy(EDX), N2 sorption, X-ray diffraction (XRD), have been used to study the formation process and characterization of the nanoparticles obtained. Transmission electron microscopy (TEM) has been applied to find out about the shape and size distribution of the particles. The nanoparticles thus synthesized were monodispersed, with an average particle size of ~ 10 nm and spherical in shape. The EDX analysis revealed the presence of Sn, O signal in the synthesized nanoparticles confirming the purity of the synthesized samples. This protocol appears promising for application in large-scale synthesis of nanoparticles. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/933
