Nano-Structured Catalysts for Energetic and Environmental Applications

Luciana Lisi

Development of nanomaterials in the modern heterogeneous catalysis is strictly related to the design of new high-performance catalysts. A good heterogeneous catalyst should have a structural organization that maximizes the amount of active centers on the surface. The catalyst design is based on dispersion of active metals on supports and/or addition of dopants or promoters affecting the metals performance through the creation of novel nano-structures. Indeed, the catalytic behavior is highly sensitive to particle size, morphology and surface structure, as well as particle-support interactions and more active structures can be formed in the transition to the nanometer range.
