The electron diffraction pattern, in agreement with the XRD measurements, correspond well to anatase crystal structure.Figure 4: TEM micrographs (a, b) and electron diffraction pattern (c, d) of the sample TIT 144 ground.The EDS analysis of the TIT 144 ground sample (Figure 5) shows that the material, except for TiO2, contains also low amount of Fe (0.3%) and S (0.6%).
