Preparation and Characterization of CeO2doped ZnOTiO2Semiconducting Nano Composite
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
In this paper a new approach entitled MechanoGelation was introduced for the synthesis of CeO2 doped ZnO-TiO2 nanocomposite (CZT).Commercial ZnO and TiO2Nanopowders are mixed at the weighted percentage of 1:1and added with different molarities (0.1M and 0.2M) of CeO2Nanopowder. Further it was processed in a wet ball milling method in isopropanol solution followed by gelation. The prepared samples are calcinated at 450oC using the furnace.The powder X-Ray Diffraction analysis confirms that the diffraction peaks and phases of ZnO, TiO2and the existence of CeO2 dopant in Nanocomposite. The Absorbance and Transmittance properties studied by UV-Visible spectroscopy, illustrate thatthe optical properties and Bandgap of the nanocomposite.The Transmission spectra is plotted by using Beer' s Law.Particle size, chemical composition, and surface morphology were studied using FESEM-EDS.
