Aerogels: The Solid Smoke in Catalysis and Water Treatment
Aerogels are highly porous materials obtained via the low-temperature sol-gel process and dried under supercritical conditions. These materials exhibit numerous fascinating properties including very high specific surface area, extraordinarily large surface-to-volume ratio, as well as extremely low density. These physical properties in addition to the reactivity of their surface chemical groups play a major role in making the aerogels of a particular interest for a variety of applications in optics, electronics, insulation, drug delivery, catalysis, adsorption, etc. The latter two applications strongly depend on the surface nature of the aerogel since the chemical reactions and physical interactions occur at the interface between the solid’s surface and the medium where the reactants/adsorbates exist. This talk will focus on how the surface-functionalization of inorganic metal oxide aerogels or doping them with various metals could have a crucial effect on the behavior of the solid material when investigated in heterogeneous catalysis as well as adsorbent for toxic effluents from aqueous media.
ABOUT THE PRESENTER
Houssam Rassy is an Associate Professor of inorganic chemistry at the American University of Beirut (Lebanon). He received his PhD in Chemistry from University Claude Bernard – Lyon I, France in 2003. He joined University Pierre et Marie Curie – Paris VI in 2003 as post-doctoral fellow before starting his independent career at AUB in 2005. His research focuses on the design of novel highly porous metal oxide aerogels via the sol-gel process and their applications in heterogeneous catalysis, removal of toxic effluents from wastewater, and selective adsorption of target molecules.
Tea/coffee will be available at 09h45.
