Abstract
The one-step synthesis of TiO2/C microspheres via solvo-thermal method were reported using titanium tetrachloride and glucose as the precursors of titanium dioxide and carbon respectively in ethanol as solvent. The morphology and the size of microspheres affected from the time and TiCl4 salt concentration parameters were studied and the optimum conditions for the preparation of them were determined. The phase analysis, microstructure investigation and the morphology of the samples were investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) methods. At the XRD spectra only the peaks related to the anatase phase of TiO2 are appeared which demonstrated to this fact that carbon at the structure of this composite is amorphous. According to the results of SEM images the diameter of the as synthesized micro-spheres was determined between 1-3 μm. The crystallite size of TiO2 particles was 28 nm measured via the modified Scherrer's formula. The morphology investigation of TiO2/C microspheres showed that, TiO2 nanoparticles are homogenously dispersed in the carbon matrix.
