Description

Titanium dioxide nanoparticles are used in various applications including environmental photocatalysis and solar cells. In this work we present the synthesis of TiO2 nanoparticles employing sol-gel methodology. The morphology, composition, particle size, surface area and band gap of these nanoparticles have been characterized and compared with a standard anatase TiO2 reference specimen exploiting several instrumental techniques namely, Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDXS), X-Ray Diffraction (XRD), Diffused Reflectance UV-VIS spectrometry (DUR-UV-VIS), Transmission Electron Microscopy (TEM), Brunauer–Emmett–Teller (BET) theory and Raman Spectrometry.
