Research activities.

The developed scientific activity involves two distinct fields of research, the renewable energy with particular attention to the process of hydrogen storage, and the field of heterogeneous catalysis.

In the field of hydrogen storage, a sector of strategic importance in the field of renewable energy the study concerned intermetallic systems (alloys Zr-Ni-V) and the development of additives (mainly ternary systems Mg-Nb-O) to improve the properties of absorption and desorption of hydrogen of the system MgH₂.

In the field of heterogeneous catalysis two aspects have been developed in these years.

The first one, more inherent to the field of surface chemistry focusing the attention on the interaction of various molecules (i.e. H₂S, SO₂, CS₂ C₂H₂, H₂O) with the oxides surface.

The second one, which represents the main research activity in heterogeneous catalysis concerns the field of photocatalysis. The developed work involves the synthesis and characterization of semiconducting oxides for photocatalytic applications, in particular using doping procedures to modify its chemical and physical properties. In this second context, the study has mainly focused on the nature of defects in solids and their role in the catalytic properties of the materials. Great attention has been spent on the TiO₂ system due to its importance in the field of photocatalysis and in particular to TiO₂ systems doped with non-metallic elements such as N, B, C and F in order to photosensitize the solid to the visible component of the solar spectrum.
