CERIC PROPOSAL ( number: 20142026): Structural characterization of HKUST-1 intercalated with conductive graphene-like layers

The aim of this proposal is the structural characterization of composite materials prepared by combining through a solvothermal co-synthesis a copper based metal organic framework (MOF type HKUST-1) and graphene-like layers. The interactions between the MOF units and the carbonaceous layers are not completely understood and they seem involved in the generation of a different porosity distribution in the composites with respect to the neat HKUST-1. With this proposal we want to go insight to these interactions by the implementation of sensitive diagnostic techniques. X-ray absorption spectroscopy (XAS) and solid state NMR are excellent techniques for characterizing the local structure of materials. In particular, the NEXAFS and XAFS techniques offer the basic knowledge for understanding the oxidation states and fine structures of metallic centers and carbonaceous part, respectively, present in our composites. High resolution NMR spectra will give complementary information to elucidate the electronic environment of C atoms.
