The catalytic activation of small molecules is particularly relevant when thinking about CO, CO2, CH4, H2O, NOx etc that nowadays can be regarded as feedstock to obtain value added chemicals and/or energy, with the view to sustainable chemistry and cleaner production. The activation of these molecules is a challenging task in catalysis, as they are very stable and require active and selective catalysts to be converted to useful products or energy carriers. In our group we have been working for nearly three decades on ceria-containing materials that can exploit the unique redox properties of ceria to boost the activity and tune the selectivity of metal-based catalysts. The research is focused on the study of metal-support interactions that can modify catalytic properties and performances, trying to understand the fundamental relationship between structure and activity. This is done by in depth material characterization, coupling conventional and in situ techniques available in our lab and in collaboration with national and international partners.
