摘要
Nanocrystalline TiO2 was synthesized by the sol-gel process by controlling the crystallite size through calcination. The resulting nanocrystals were characterized using XRD, FT-Raman, SEM/EDX, DSC/TGA and UV-Vis spectroscopic techniques. XRD patterns confirmed the presence of only pure 100% anatase phase TiO2 The surface morphology of the nanotitania was evaluated with Scanning Electron Microscopy. The purity of the sol-gel-derived TiO2 was confirmed through EDX measurements. The band gap of the nanotitania was found to be 3.6 eV from UV-Vis measurements. The pHzpc of the titania sample was measured as 5.90. (c) 2006 Elsevier Inc. All rights reserved.
