  • Application of High-resolution NMR and DNP spectroscopy for molecular understanding of heterogeneous catalysis, the reactions mechanism and solid materials.

High resolutions NMR provides a range of exquisitely precise tools to characterize Well-defined active sites in heterogeneous catalysis. Implementation of high resolution and 2D solid state NMR and DNP techniques helped to identify surface structures at a molecular level, which is a key to implementing structure–reactivity relationships and rational developments in heterogeneous catalysis. It is clear that these methods also have the potential for extensive further developments and applications, for example probing the dynamics of surface species, access to mobility of active sites),  and to monitor the active sites as a function of time.

2D high resolution and 2D NMR and DNP spectra shows the power of this technique to characterize the well-defined heterogeneous  and different reactions catalysts prepared and others modern solid materials:

  1. Supported well defined single site organometallic catalysis:  These notions are the basis of the “catalysis by design” strategy (“structure–activity” relationship) in which a better understanding of the mechanistic aspects of the catalytic process led to the improvement of catalyst performances.
  2. The role of different Zeolites and its reactions such (as  methanol-to-hydrocarbon process, direct conversion of CO2 to light olefins and Aromatics, Aromatization of Ethylene, methane dehydroaromatization, ……)
  3. The binding mode of organic ligands to nanoparticles surfaces: gold is one of the most active and dynamic areas of chemistry
  4. Advanced study of Crystalline polymers that are important materials with myriad Applications: Polymer characterization by NMR provides detailed structural information for product development and quality control considerations
  5. Metal-organic frameworks (MOFs) are a new type of porous materials with numerous current and potential applications in many areas including ion-exchange, catalysis, sensing, separation, molecular recognition, drug delivery and, in particular gas storage. Solid-state NMR (SSNMR) has played a pivotal role in structural characterization and understanding of host-guest interactions in MOFs.
  6. NMR as a powerful tool to study ion batteries (7Li, 23Na,39K,…)
  7. Structure, dynamic, electronic and magnetic properties of carbon nanotubes and derivatives family
