It is noteworthy that by modifying the thermal treatment, materials with different morphology
and properties can be obtained. The surface properties and the structure of the so-obtained
materials have been investigated by means of SEM and AFM microscopies, ex-situ EXAFS
techniques, XRD analysis and Raman spectroscopy.
