Session Abstract | ||
Catalysis and MOFs: Materials structure and function in chemical applications using crystallography and XAFS Metal Organic Frameworks (MOFs) are a recent class of porous materials. On one hand, their crystalline characteristics with tunable porous structure with high surface areas and large pore volumes similar to that of zeolites and the ease of access to various metals ions in the pore resulting from their compositional versatility make them very attractive for catalysis. On the other hand, the channel of MOFs can serve also as host of active metal nanoparticles preserving them from undesirable sintering or modifications during reactions leading to deactivation. XRD and EXAFS are both powerful techniques to characterize the structures of those porous materials and fate of the embedded active species, single metal ions or nanoparticles. This MS will highlight how complementary are those techniques to help the researchers into the design of efficient catalysts using MOF materials and derived carbonaceous supports.
