Control of Particle Characteristics in the Preparation of TiO 2 Nano Particles Assisted by Microwave

nanostructures with various morphologies like cubes, spheres, hexahedral pillars and spherical tubes were synthesized by microwave-assisted hydrothermal process. Each structure was obtained by changing the relative concentrations of titanium tetraisoproxide (TTIP), tetrabutylammonium hydroxide (TBAH) and ethanol. Scanning electron microscopy (SEM), transmission electoron microscopy (TEM), X-ray diffraction and Brunauer-Emmett-Teller (BET) surface area analysis were used to characterize the synthesized nanostructures. From these results, it has been proved that structure could be controlled to have specific morphology, size, surface area, pore volume and pore size distribution.
