New energetic nanomaterials synthesis

Synthesis of nanoparticles for energetic applications

Principal investigators: Angela Gondolini, Alessandra Sanson

Involved personnel: Elisa Mercadelli

Besides the process technologies used, the successful production of highly efficient ceramics is strictly related to the chemical-physical characteristics of the starting powders. For this objective, CNR-ISTEC has implemented a conventional synthesis method applying innovative heating systems for the production of ceria-based powders or perovskite-related systems with high chemical-physical reactivity and high purity and morphological control. These systems have been exploited for catalytic applications such as toluene synthesis and as high-efficient electrolytic powders for SOFC/SOEC applications as well as for solar conversion processes.
