Abstract:

The main objective of this study is the synthesis and characterization of nanocrystalline anatase TiO2 in microwave-assisted hydrothermal conditions. The synthesis was successfully performed in a microwave reaction system, Multiwave 3000, produced by Anton Paar at 2.45 GHz for a continuous power of 1000W. The structural and morphological characterization has been investigated by X-ray diffraction, DRUV-VIS spectroscopy, BET surface area analysis, SEM microscopy and EDX analysis. The material purity was confirmed by EDX elemental analysis. Results showed that the synthesized nanocrystalline TiO2 contained mainly anatase phase with crystallite size of 10 nm calculated by Scherrer’s relation and also confirmed by SEM images.


Keywords: microwave-assisted hydrothermal, TiO2, nanometer size, nanocrystalline
