Abstract:

Colloidal synthesis has been regarded as a useful tool to prepare reliable model catalysts due to the control on size, shape and composition that can be achieved at the nanoscale using this method. One interesting class of tailored colloidal nanomaterials is represented by the so-called dumbbell like metal-metal oxide heterodimers, developed for catalytic and biomedical applications. This structure is characterized by the fact that one metallic domain is epitaxially connected and partially nested inside one oxide domain, both domains having a size in the nanometers range. This morphology is particularly interesting for heterogeneous catalysis applications because of the structural stability and the high sintering resistance of the metal domains, which is one of the main causes of deactivation in traditional metal supported catalysts. The catalytic activity of this type of materials can be carefully tuned thanks to colloidal chemistry by playing with the size and the composition of both the metallic and the oxide domains, leading to the development of active and stable oxidation catalysts. This contribution will review the work done at the Italian Institute of Technology in this specific field.
