The activity of the group is focused on the preparation of nanostructures of reducible oxides, on their structural and morphological characterization and on the investigation of their catalytic performances. The modulation of metal-support interaction in hierarchical metal@ceria core-shell catalysts allows the achievement of improved redox properties and exceptional high catalytic reactivity and long term stability, such as that observed in methane oxidation. The use of monodispersed metals nanocrystals deposited on ceria represent a suitable approach to identify active catalytic sites for industrially important catalytic reaction such as CO oxidation. The investigation of supported Fe2O3 polymorphs and of TiO2 nanocrystals as photocatalysts for Hydrogen Evolution Reaction (HER) aims of proving the importance of nanostructure in driving the reactivity.
